Exact Match

["Wilton, Reece" <Re...@dig.com>]

Hi,

Does Lucene support exact matching on a tokenized field?

So for example... if I add these three phrases to the index:
- "The quick brown fox"
- "The quick brown fox jumped"
- "brown fox"

I want to be able to do an exact field match so when I search for "brown
fox" I only get the last one returned.  I can do this in my own code by
storing the data and then comparing it to the search phrase.  Is that
the best way of doing this?

Thanks,
Reece

Why not just use an untokenized field?  Then just use a TermQuery, 
searching for the term "brown fox".

There is no direct support for that.  However, if one of your documents
contains _only_: "brown fox", won't a search for "brown fox" give that
document the highest score, as it is the closest match, allowing you to
just pop the first hit?  It's no guarantee that the first hit is the
exact match (what if there are no exact matches in the index), but
that's a simple check to perform in your application.
