  • MySQL Full-text Search Workaround for innoDB tables

    - by Rob
    I'm designing an internal web application that uses MySQL as its backend database. The integrity of the data is crucial, so I am using the innoDB engine for its foreign key constraint features. I want to do a full-text search of one type of records, and that is not supported natively with innoDB tables. I'm not willing to move to MyISAM tables due to their lack of foreign key support and due to the fact that their locking is per table, not per row. Would it be bad practice to create a mirrored table of the records I need to search using the MyISAM engine and use that for the full-text search? This way I'm just searching a copy of the data and if anything happens to that data it's not as big of a deal because it can always be re-created. Or is this an awkward way of doing this that should be avoided? Thanks.

  • Reverse Search Best Practices?

    - by edub
    I'm making an app that has a need for reverse searches. By this, I mean that users of the app will enter search parameters and save them; then, when any new objects get entered onto the system, if they match the existing search parameters that a user has saved, a notification will be sent, etc. I am having a hard time finding solutions for this type of problem. I am using Django and thinking of building the searches and pickling them using Q objects as outlined here: http://www.djangozen.com/blog/the-power-of-q The way I see it, when a new object is entered into the database, I will have to load every single saved query from the db and somehow run it against this one new object to see if it would match that search query... This doesn't seem ideal - has anyone tackled such a problem before?

  • fastest way to perform string search in general and in python

    - by Rkz
    My task is to search for a string or a pattern in a list of documents that are very short (say 200 characters long). However, say there are 1 million documents of such time. What is the most efficient way to perform this search?. I was thinking of tokenizing each document and putting the words in hashtable with words as key and document number as value, there by creating a bag of words. Then perform the word search and retrieve the list of documents that contained this word. From what I can see is this operation will take O(n) operations. Is there any other way? may be without using hash-tables?. Also, is there a python library or third party package that can perform efficient searches?

  • In Chrome, is there a way to search only within my bookmarked sites?

    - by McGirl
    I'm not trying to search for a bookmark - I'm trying to search for a term that may appear on one of my bookmarked sites. For instance, if I wanted to search on the term "Obama" and restrict my query to the New York Times web site, I know I could type this into the main URL/Search bar in Chrome: obama site:nytimes.com I'm wondering if there's a way to change that so that it's effectively: obama site:any one of the sites in my Chrome bookmark folder Thanks in advance for your help!

  • "I'm Feeling Lucky"-style behavior in Windows 8.1 search?

    - by vorou
    Is it possible to make Windows 8.1 automatically select the most relevant search result, so that I could just press Enter to execute it? Right now, I have to press down-arrow each time to select it, and then press Enter. I occasionally forget to press the down-arrow, and Windows opens that very useful Search Results window for me. It makes me sad since I'm absolutelly happy with the top search result nearly all the time. P.S.: I'm taking about the Search in Start menu (the menu which opens when I press winkey)

  • How to create managed properties at site collection level in SharePoint2013

    - by ybbest
    In SharePoint2013, you can create managed properties at site collection. Today, I’d like to show you how to do so through PowerShell. 1. Define your managed properties and crawled properties and managed property Type in an external csv file. PowerShell script will read this file and create the managed and the mapping. 2. As you can see I also defined variant Type, this is because you need the variant type to create the crawled property. In order to have the crawled properties, you need to do a full crawl and also make sure you have data populated for your custom column. However, if you do not want to a full crawl to create those crawled properties, you can create them yourself by using the PowerShell; however you need to make sure the crawled properties you created have the same name if created by a full crawl. Managed properties type: Text = 1 Integer = 2 Decimal = 3 DateTime = 4 YesNo = 5 Binary = 6 Variant Type: Text = 31 Integer = 20 Decimal = 5 DateTime = 64 YesNo = 11 3. You can use the following script to create your managed properties at site collection level, the differences for creating managed property at site collection level is to pass in the site collection id. param( [string] $siteUrl="http://SP2013/", [string] $searchAppName = "Search Service Application", $ManagedPropertiesList=(IMPORT-CSV ".\ManagedProperties.csv") ) Add-PSSnapin Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue $searchapp = $null function AppendLog { param ([string] $msg, [string] $msgColor) $currentDateTime = Get-Date $msg = $msg + " --- " + $currentDateTime if (!($logOnly -eq $True)) { # write to console Write-Host -f $msgColor $msg } # write to log file Add-Content $logFilePath $msg } $scriptPath = Split-Path $myInvocation.MyCommand.Path $logFilePath = $scriptPath + "\CreateManagedProperties_Log.txt" function CreateRefiner {param ([string] $crawledName, [string] $managedPropertyName, [Int32] $variantType, [Int32] $managedPropertyType,[System.GUID] $siteID) $cat = Get-SPEnterpriseSearchMetadataCategory –Identity SharePoint -SearchApplication $searchapp $crawledproperty = Get-SPEnterpriseSearchMetadataCrawledProperty -Name $crawledName -SearchApplication $searchapp -SiteCollection $siteID if($crawledproperty -eq $null) { Write-Host AppendLog "Creating Crawled Property for $managedPropertyName" Yellow $crawledproperty = New-SPEnterpriseSearchMetadataCrawledProperty -SearchApplication $searchapp -VariantType $variantType -SiteCollection $siteID -Category $cat -PropSet "00130329-0000-0130-c000-000000131346" -Name $crawledName -IsNameEnum $false } $managedproperty = Get-SPEnterpriseSearchMetadataManagedProperty -Identity $managedPropertyName -SearchApplication $searchapp -SiteCollection $siteID -ErrorAction SilentlyContinue if($managedproperty -eq $null) { Write-Host AppendLog "Creating Managed Property for $managedPropertyName" Yellow $managedproperty = New-SPEnterpriseSearchMetadataManagedProperty -Name $managedPropertyName -Type $managedPropertyType -SiteCollection $siteID -SearchApplication $searchapp -Queryable:$true -Retrievable:$true -FullTextQueriable:$true -RemoveDuplicates:$false -RespectPriority:$true -IncludeInMd5:$true } $mappedProperty = $crawledproperty.GetMappedManagedProperties() | ?{$_.Name -eq $managedProperty.Name } if($mappedProperty -eq $null) { Write-Host AppendLog "Creating Crawled -> Managed Property mapping for $managedPropertyName" Yellow New-SPEnterpriseSearchMetadataMapping -CrawledProperty $crawledproperty -ManagedProperty $managedproperty -SearchApplication $searchapp -SiteCollection $siteID } $mappedProperty = $crawledproperty.GetMappedManagedProperties() | ?{$_.Name -eq $managedProperty.Name } #Get-FASTSearchMetadataCrawledPropertyMapping -ManagedProperty $managedproperty } $searchapp = Get-SPEnterpriseSearchServiceApplication $searchAppName $site= Get-SPSite $siteUrl $siteId=$site.id Write-Host "Start creating Managed properties" $i = 1 FOREACH ($property in $ManagedPropertiesList) { $propertyName=$property.managedPropertyName $crawledName=$property.crawledName $managedPropertyType=$property.managedPropertyType $variantType=$property.variantType Write-Host $managedPropertyType Write-Host "Processing managed property $propertyName $($i)..." $i++ CreateRefiner $crawledName $propertyName $variantType $managedPropertyType $siteId Write-Host "Managed property created " $propertyName } Key Concepts Crawled Properties: Crawled properties are discovered by the search index service component when crawling content. Managed Properties: Properties that are part of the Search user experience, which means they are available for search results, advanced search, and so on, are managed properties. Mapping Crawled Properties to Managed Properties: To make a crawled property available for the Search experience—to make it available for Search queries and display it in Advanced Search and search results—you must map it to a managed property.

  • my Search method is coming up with all nulls

    - by Epic.Distortion
    Let me give a quick explanation. I took a 5 week course through a company on Java in July. They covered basic stuff, like console app, crud operations, mysql, and n-tier architecture. Since the course ended I didn't use it much because I went back to work, and other medical reasons surfaced....blah blah. I was told by the company to make a simple program to reflect what I learned. Turns out I retained very little. I decided to make a video game starage program. It would be used to stare your video games so you wouldn't have to search your bookcase(or how ever you store your games.) It is a basic console app using the crud operations with MYSQL. I can't get my search function to actually work. I have 2 layers a Presentation layer and a Logic layer. The search method allows them to search for a game by the title. when i bring run the program and use Search it only displays the title and the rest is null. here is my Presentation layer: private static Games SearchForGame() { Logic aref = new Logic(); Games g = new Games(); Scanner scanline = new Scanner(System.in); System.out.println("Please enter the name of the game you wish to find:"); g.setTitle(scanline.nextLine()); aref.SearchGame(); System.out.println(); System.out.println("Game Id: " + g.getGameId()); System.out.println("Title: " + g.getTitle()); System.out.println("Rating: " + g.getRating()); System.out.println("Platform: "+ g.getPlatform()); System.out.println("Developer: "+ g.getDeveloper()); return g; } and here is my logic layer public Games SearchGame() { Games g = new Games(); try { Class.forName(driver).newInstance(); Connection conn = DriverManager.getConnection(url+dbName,userName,password); java.sql.PreparedStatement statement = conn.prepareStatement("SELECT GameId,Title,Rating,Platform,Developer FROM games WHERE Title=?"); statement.setString(1, g.getTitle()); ResultSet rs = statement.executeQuery(); while(rs.next()){ g.setGameId(rs.getInt("GameId")); g.setTitle(rs.getString("Title")); g.setRating(rs.getString("Rating")); g.setPlatform(rs.getString("Platform")); g.setDeveloper(rs.getString("Developer")); statement.executeUpdate(); } } catch (Exception e) { e.printStackTrace(); } return g; } here is also my last results Please enter the name of the game you wish to find: Skyrim Game Id: 0 Title: Skyrim Rating: null Platform: null Developer: null any help would be greatly appreciated and thanks in advance EDIT: here is my code for my games class public class Games { public int GameId; public String Title; public String Rating; public String Platform; public String Developer; public int getGameId() { return GameId; } public int setGameId(int gameId) { return GameId = gameId; } public String getTitle() { return Title; } public String setTitle(String title) { return Title = title; } public String getRating() { return Rating; } public void setRating(String rating) { Rating = rating; } public String getPlatform() { return Platform; } public void setPlatform(String platform) { Platform = platform; } public String getDeveloper() { return Developer; } public void setDeveloper(String developer) { Developer = developer; } }

  • Failed to load viewstate.The control tree into which viewstate is being loaded...etc

    - by alaa9jo
    Two days ago,a colleague of mine tried to publish an asp.net website (which is built in VS2008 using framework 3.5) to our server,he configured everything in IIS (he made sure that the selected asp.net version is 2.0) and launched the website..at first it was working great but when he tried to click on a specific treeview...BOOM..: "Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request." In that page there were these control: a TreeView and a Placeholder,when the user selects any node then it's controls will be created dynamically into that placeholder..for the first time it's working fine but when (s)he select another node then that issue appears. He called me to help him with this issue,for me this is the first time I see such an issue,scratch my head then I decided to eliminate the possibilities of this issue one by one,at the development machine it's working perfectly,he published the website at the local IIS and again..it's working perfectly,I took a copy of the website and published it into my laptop but no issues at all,so this is means that it's not an issue in the code. So there is something missing/wrong in our server [it has Windows Server 2003],we went to the server and checked on the web-config and the configurations on IIS...nothing wrong so far,so I decided to check if the framework 3.5 is installed or not and the answer: it wasn't installed Of course he assumed that it was installed and there was nothing to tell if it wasn't from the "ASP.Net version" in IIS because frameworks 3.0 and 3.5 will not be listed there [2.0 will be listed there instead],the only way to check if it was installed or not is to search for the framework in this path:[WINDOWS Folder]\Microsoft.NET\Framework or check if it was installed in Add or remove programs. The obvious solution for his case: We installed Framework 3.5 SP1 into our server,did a restart to the machine and it worked ! If anyone faced the same issue and solved it using the same solution or with a different one please post it here to share experience.

  • Two "search" entries in resolv.conf

    - by Carsten
    I am using 12.04 and have a problem with my resolv.conf There are 2 search lines there. But I can only explain one. I would like to get the other one removed. carsten@myubuntubox:~$ cat /etc/resolv.conf # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8) # DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN nameserver 127.0.0.1 search aaaa.bbb.example.net search something nameserver 1.2.3.4 nameserver 1.2.3.5 I can't explain the search aaaa.bbb.example.net Where does it come from? The last 3 lines (like I want come from /etc/resolvconf/resolv.conf.d/tail This is good. But where is the other search line coming from? In /etc/dhcp/dhclient I removed the requests for domain-name-servers, domain-search, but the lines are still in there. Should I remove the dhcp6.domain-search as well?

  • How exactly is an Abstract Syntax Tree created?

    - by Howcan
    I think I understand the goal of an AST, and I've build a couple of tree structures before, but never an AST. I'm mostly confused because the nodes are text and not number, so I can't think of a nice way to input a token/string as I'm parsing some code. For example, when I looked at diagrams of AST's, the variable and its value were leaf nodes to an equal sign. This makes perfect sense to me, but how would I go about implementing this? I guess I can do it case by case, so that when I stumble upon an "=" I use that as a node, and add the value parsed before the "=" as the leaf. It just seems wrong, because I'd probably have to make cases for tons and tons of things, depending on the syntax. And then I came upon another problem, how is the tree traversed? Do I go all the way down the height, and go back up a node when I hit the bottom, and do the same for it's neighbor? I've seen tons of diagrams on ASTs, but I couldn't find a fairly simple example of one in code, which would probably help.

  • String Occurance Counting Algorithm

    - by Hellnar
    Hello, I am curious what is the most efficient algorithm (or commonly used) to count the number of occurances of a string in a chunck of text. From what I read, Boyer–Moore string search algorithm is the standard for string search but I am not sure if counting occurance in an efficient way would be same as searching a string. In python this is what I want: text_chunck = "one two three four one five six one" occurance_count(text_chunck, "one") # gives 3. Regards EDIT: It seems like python str.count serves me such method however I am not able to find what algorithm it uses.

  • Alternative to Google Custom Search

    Hi, I'm using Google Custom Search (http://www.google.com/cse) on a client website. They are not very happy about rival companies showing up on sponsered links on their own site. I know we can use Google Site Search (http://www.google.com/sitesearch/ but it has an annual fee. I've been looking all around for a Free/OpenSource alternative for Google CSE, but found little I can use. Anyone have any suggestions? Thank you
