There are quite a few ways to do this...you just read in the file to
create a list of the words and when your query parser sees the right
keyword either use a TokenFilter that expands to each word or just add
each word to a BooleanQuery as a Should clause (or expand to a proper
Lucene syntax string). This is basically just a thesaurus and you
shouldn't find it too terribly difficult to implement.

I have looked around on Lucene web site as well as some documentation
but have not found anything to do with Concept Search.
My definition of Concept Search is as follows:
1. I would have a file (list) of various phrases / N-grams which I
would like to Lucene to use as a search basis without having to type in
all these phrases manually, and have Lucene return the results as it
would normally if a single search query was entered.
2. An example would be - find !Wild_Animals! - where the "!" would
indicate that this is a search that would use a file (ie
Wild_Animals.txt) and read in the various phrases within this file and perform the
search in the corpus for these phrases.
3. The contents of Wild_Animals.txt could look like this:
BUFFALO
BEAR
MOOSE
COYOTE
WOLF
MOUNTAIN GOAT
MOUNTAIN SHEEP
DALL SHEEP
DEER
KODIAK BEAR
BROWN BEAR
BLACK BEAR
etc etc etc
4. Is my idea of a Concept Search feasible / doable??? If so, can
you point me to any documentation that exists whereby this could be done
within Lucene
Please send any info you have on this to me -
