Lucene Search Returning Extra, Undesired Records
- by Brandon
I have a Lucene index that contains a field called 'Name'.
I escape all special characters before inserting a value into my index using QueryParser.Escape(value).
In my example I have 2 documents with the following names respectively:
Test
Test (Test)
They get inserted into my index as such (I can confirm this using Luke):
[test]
[test] [\(test\)]
I insert these values as TOKENIZED and using the StandardAnalyzer.
When I perform a search, I use the QueryParser.Escape(searchString) against my search string input to escape special characters and then use the QueryParser with my 'Name' field and the StandardAnalyzer to perform my search.
When I perform a search for 'Test', I get back both documents in my index (as expected). However, when I perform a search for 'Test (Test)', I am getting back both documents still.
I realize that in both examples it matches on the 'test' term in the index, but I am confused in my 2nd example why it would not just pull back the document with the value of 'Test (Test)' because my search should create two terms:
[test] and [\(test\)]
I would imagine it would perform some sort of boolean operator where BOTH terms must match in that situation so I would get back just one record.
Is there something I am missing or a trick to make the search behave as desired?
