  • Search implementation dilemma: full text vs. plain SQL

    - by Ethan
    I have a MySQL/Rails app that needs search. Here's some info about the data: Users search within their own data only, so searches are narrowed down by user_id to begin with. Each user will have up to about five thousand records (they accumulate over time). I wrote out a typical user's records to a text file. The file size is 2.9 MB. Search has to cover two columns: title and body. title is a varchar(255) column. body is column type text. This will be lightly used. If I average a few searches per second that would be surprising. It's running an a 500 MB CentOS 5 VPS machine. I don't want relevance ranking or any kind of fuzziness. Searches should be for exact strings and reliably return all records containing the string. Simple date order -- newest to oldest. I'm using the InnoDB table type. I'm looking at plain SQL search (through the searchlogic gem) or full text search using Sphinx and the Thinking Sphinx gem. Sphinx is very fast and Thinking Sphinx is cool, but it adds complexity, a daemon to maintain, cron jobs to maintain the index. Can I get away with plain SQL search for a small scale app?

  • iPhone Multithreaded Search

    - by Kulpreet
    I'm sort of new to any sort of multithreading and simply can't seem to get a simple search method working on a background thread properly. Everything seems to be in order with an NSAutoreleasePool and the UI being updated on the main thread. The app doesn't crash and does perform a search in the background but the search results yield the several of the same items several times depending on how fast I type it in. The search works properly without the multithreading (which is commented out), but is very slow because of the large amounts of data I am working with. Here's the code: - (void)filterContentForSearchText:(NSString*)searchText { isSearching = YES; NSAutoreleasePool *apool = [[NSAutoreleasePool alloc] init]; /* Update the filtered array based on the search text and scope. */ //[self.filteredListContent removeAllObjects]; // First clear the filtered array. for (Entry *entry in appDelegate.entries) { NSComparisonResult result = [entry.gurmukhiEntry compare:searchText options:(NSCaseInsensitiveSearch|NSDiacriticInsensitiveSearch) range:NSMakeRange(0, [searchText length])]; if (result == NSOrderedSame) { [self.filteredListContent addObject:entry]; } } [self.searchDisplayController.searchResultsTableView performSelectorOnMainThread:(@selector(reloadData)) withObject:nil waitUntilDone:NO]; //[self.searchDisplayController.searchResultsTableView reloadData]; [apool drain]; isSearching = NO; } - (BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString { if (!isSearching) { [self.filteredListContent removeAllObjects]; // First clear the filtered array. [self performSelectorInBackground:(@selector(filterContentForSearchText:)) withObject:searchString]; } //[self filterContentForSearchText:searchString]; return NO; // Return YES to cause the search result table view to be reloaded. }

  • How do I add text to an animated .gif in gimp?

    - by Carla
    I have just worked out how to create an animated.gif in gimp but I am having a problem adding text. When I create/add the text box and then save my.gif and view it, the text only flashes up over one frame/layer. How do I make the text last over the entire duration of the animated.gif? If you could explain in very simple terms, with the easiest solution, that would be wonderful as I am quite new to all this and very unsure of what I am doing! Thank you for any help you can give.

  • Full text searching in SQL Server 2008 Express Advanced

    - by Iain Macleod
    Hi, I have recently installed SQL Server 2008 Express Edition with Advanced Services on XP Pro but am having trouble getting full text searching to work with an restored database. The database was originally created in SQL Server 2005. When I call a stored proc that uses the full text index then I get the following error: Full-Text Search is not installed, or a full-text component cannot be loaded. This is my db version: Microsoft SQL Server 2008 (RTM) - 10.0.1600.22 (Intel X86) Jul 9 2008 14:43:34 Copyright (c) 1988-2008 Microsoft Corporation Express Edition with Advanced Services on Windows NT 5.1 (Build 2600: Service Pack 3) When I run: SELECT DATABASEPROPERTY('DBNAME','ISFULLTEXTENABLED') I get: 1 Also, when I look in the advanced properties for the db server in Management Studio I see both the "Default Full-Text Language" and "Full-Text Upgrade Option" properties. However, when I go to SQL Server Configuration Manager I don't see the "MSSQLFDLauncher" service. Does anyone know how to get this working? Cheers, Iain

  • How to select all text inside text area of code field on web pages

    - by Moorage
    In all the forums web pages the download links are given inside the [code] braces that looks like text area with white background. When the download links are in large numbers then there are scroll bars. I find it difficult to scroll up and then select and then drag down to select all links. Is there any way to select all , when I click on select all on right click then it usually selects the text from whole page not from that code segment

  • How can I make the text cursor in X Windows easier to see?

    - by skyblue
    The text cursor in X Windows is too thin for me to see easily. It would be great if I could make the text cursor wider so that it was more visible. I know how to change the size of the mouse cursor in X by going to System Preferences Appearance and customizing the Pointer so that it is larger. But I have not been able to find any setting that allows me to alter the appearance of the text cursor. So how can I make the text cursor easier to see?

  • Dolphin search bar missing. How can i get it back?

    - by Ike
    A while ago, my search bar went missing in dolphin. If the search toolbar is checked for view/unhide, nothing shows up. I noticed if i check and uncheck the button to hide/unhide it, a small, thin content-less bar slightly pushes the rest of the toolbar up. i tried reconfiguring with dpkg, purging and reinstalling, etc. i left it alone as i thought it would be fixed in an update, but today i upgraded daolphin and it's still gone. any thoughts?

  • Displaying thumbnails in google search results for flash games?

    - by serg
    Some sites are somehow displaying video preview thumbnails for pages that contain flash games in google search results. For example search for: site:www.thorgaming.com game I see this only on small sites which makes me believe google is not very happy about it. How do they do it and is it ok with google? I assume they are submitting thumbnails through video sitemaps, but I can't find any information about using them with flash games. I also run a few such sites through rich snipped testing tool and it didn't detect any microdata tags on a page.

  • How can I create multiple mini-sites with similar/duplicate content without hurting my search engine rank?

    - by ekpyrotic
    Essential background: I run a small company that lets members of the public post handwritten letters to their local politician (UK-based). Every week a number of early stage bills (called Early Day Motions) are submitted for debate in the House of Commons, and supporters of the motion will contact their local Members of Parliament, asking them to sign the motion. The crux: I want to target these EDMs with customised mini-sites, so when people search "EDM xxx", they find my customised mini-site, specifically targeting that EDM (i.e., "Send a handwritten letter to your MP asking them to sign EDM xxx"). At the moment, all these mini-sites (and my homepage) have duplicate content with only the relevant EDM name, number, and background image changed. (For example, http://mailmymp.com and http://mailmymp.com/edm/teaching-life-saving-skills-at-school-edm-550.php). The question: Firstly, will this hurt my potential search engine ranking? And, if so, what's the best way to target these political campaigns in an efficient manner without hurting my SEO prospects?

  • Search string in file (C)

    - by chutsu
    So my code isn't working... test.c:27: warning: passing argument 1 of ‘search’ from incompatible pointer type which is the fgets line. My code opens a file, reads the file line by line, and I'm trying to create a "search" function that will return a value that indicates whether that string is found on that line of the file. My ultimate goal is to achieve a search and replace program. But one step at a time eh? this is what I have so far: #include <stdio.h> #include <string.h> int search(const char *content[], const char *search_term) { int t; for(t=0; content[t]; ++t){ if(!strcmp(content[t], search_term)){ return t; // found } } return 0; // not found } int main(int argc, char *argv[]) { FILE *file; char line[BUFSIZ]; int linenumber=0; char term[20] = "hello world"; file = fopen(argv[1], "r"); if(file != NULL){ while(fgets(line, sizeof(line), file)){ if(search(line, term) != -1){ printf("Search Term Found!!\n"); } ++linenumber; } } else{ perror(argv[1]); } fclose(file); return 0; }

  • Lining up the text in a tool tip, with the text in a combobox

    - by Steve P
    I see a lot of programs where if the text doesn't fit inside the bounds of the control, you can put your mouse over the control and the tooltip text will show you the full unclipped text, and also the tooltip text lines up completly with the text in the control. I'm trying to do that with a combobox in VB 2005 (.net version 2.0). In the tooltip draw event I've tried setting the tooltip location to the location of the AssociatedControl.DisplayRectangle, and the AssociatedControl.ClientRectangle. Each of these seem to put the tooltip text in the top left corner of the combobox, just slightly offset from the text in the combobox. Is there some type of padding I need to account for? or what's going on here?

  • Get context for search string in text in C#

    - by soundslike
    Given a string text which contains newline there is a search keyword which matches an item within the text. How do I implement the following in C#: searchIdx = search index (starting with 0, then 1, etc. for each successive call to GetSearchContext. Initially start with 0. contextsTxt = string data to search in searchTxt = keyword to search for in contextsTxt numLines = number of lines to return surrounding the searchTxt found (ie. 1 = the line the searchTxt is found on, 2 = the line the searchTxt is found on, 3 = the line above the searchTxt is found on, the line the searchTxt is found on, and the line below the searchTxt is found on) returns the "context" based on the parameters string GetSearchContext(int searchIdx, string contentsTxt, string searchTxt, int numLines); If there's a better function interface to accomplish this feel free to suggest that as well. I tried the following but doesn't seem to work properly all the time: private string GetSearchContext(string contentValue, string search, int numLines) { int searchIdx = contentValue.IndexOf(search); int startIdx = 0; int lastIdx = 0; while (startIdx != -1 && (startIdx = contentValue.IndexOf('\n', startIdx+1)) < searchIdx) { lastIdx = startIdx; } startIdx = lastIdx; if (startIdx < 0) startIdx = 0; int endIdx = searchIdx; int lineCnt = 0; while (endIdx != -1 && lineCnt++ < numLines) { endIdx = contentValue.IndexOf('\n', endIdx + 1); } if (endIdx == -1 || endIdx > contentValue.Length - 1) endIdx = contentValue.Length - 1; string lines = contentValue.Substring(startIdx, endIdx - startIdx + 1); if (lines[0] == '\n') lines = lines.Substring(1); if (lines[lines.Length - 1] == '\n') { lines = lines.Substring(0, lines.Length - 1); } if (lines[lines.Length - 1] == '\r') { lines = lines.Substring(0, lines.Length - 1); } return lines; }

  • Will a search engine lower the rank of my page if i have hidden iframes?

    - by Skurpi
    As a praxis, all external content on our site is put in iframes to lower the risks of any external parties injecting stuff to our users. We also do it to make sure our content shows up before banners, to make the site feel quicker. We now have an external script running which we want to put in an iframe, but it does not have any visible content to go with it so I want to put css "visibility: hidden;" on the iframe. I read in a forum somewhere that search engines will lower the rank of a page, or even drop the page, if a iframe has "the minimal size of 1x1px". Will a search engine lower the rank of my page if I have a hidden (or 1px big) iframe?
