Re: Performing exact search with Lucene

[Steven Rowe]

Phil,

If you *really* want exact matching against documents, you could put the
document content into a keyword field (that is, one field per doc, with
no tokenization), then search with your query as a single term, rather
than tokenized into separate terms.  This way, you're guaranteed a match
only if the match is complete and exact.
Of course, if you don't *really* mean exact matching (e.g., if you want
to allow multiple spaces between words, or for newlines to substitute
for spaces, etc.), then you'll have to find a different solution.

Thanks for your quick answer. I'm going to try the PhraseQuery as you 
propose.

But considering theses three examples :

document 1 =    "this is an example"
document 2 =    "this is an example of document"
document 3 =    "this is an other example"
i guess that a PhraseQuery, based on :

   +"this is an example"

and with setSlop(0) will match document1 AND also document2 ?

Does the PhraseQuery act as the SQL operator  LIKE  
"%something_to_search%" or like the '=' SQL operator ?

I'm going to investigate.

Thanks again.

Philippe
