Exact match search
Hi,
I want to match documents that exactly equal a certain value, not just
contain it.
If I search for "foo" in Lucene I get back documents like these:
"foo"
"foo bar"
"bar foo"
Is there a way to just get the ones that exactly
equal the value I'm searching for? In this case, I want to only return the
first document (ex. "foo").
I have a workaround where I store all the values
and then after I get the hits I go through them and skip those that don't
match. But this will return result sets of hundreds of documents that I don't
need.
Help!

How do you go about getting an exact match for a document that can contain
hundreds of words? As I understand it, when you tokenize a document it is
broken into words so really all the results you show are exact matches.

Just don't tokenize your Fields, and make sure that the query also doesn't
get tokenized (the easiest way to ensure that is probably to not use
QueryParser but just build a TermQuery directly from the user's input).
