Hi all
I have a small problem and unable to figure out how to do to it.
I am unable to figure out how do i compute similarity ( similar to the score
given by lucene) for a particular doucment indexed by lucene
and a given query string. i know that there is a function called search
which comptues

Have you considered evaluating doc-score thresholds for limiting your
results? Since the perfect answers to these situa
t I'm pretty sure it's not the tokenizing since I'm seeing
the problem with single-word entries.
Thanks for your assistance. It's been very helpful in getting me this
far.

For now, the best I could come up with is the following scheme
SAMPLE DOCUMENTS:
Lets say there are four documents:
Doc1: st louis, missouri, usa
Doc2: st louis du ha ha, quebec, canada
Doc3: new york, NY, united states of america
Doc4: ny, usa
INDEX PHASE:
-
).
4) We don't want to return Albany unless the user has Albany in the
query.
Thanks again for looking at this.

Few questions.
(1) Does each document contain only one geographical location?
(2) Given a document, how are you tokenizing it into city, state and
country? I am assuming "," as the delimiter here. Otherwise determining the
boundary for names like "St. Louis du Ha Ha" would be difficult.
(3) Are t
uery.add(query, BooleanClause.Occur.MUST);
QueryFilter filter = new QueryFilter(filterQuery);
Hits hits = searcher.search(geographyQuery, filter);
return hits;
}

Hi Colin,
Even assuming you came up with a good way of indexing, the
example query "Ontario, CA" should yield 3 hits. All 2, 3 and 4 are
valid retrievals. Could you please justify which 2 hits you want and why?
Thanks,
