You mean you'd like a BooleanQuery.setMaximumNumberShouldMatch()
method? Unfortunately that doesn't exist and I can't think of a
simple way of doing it.

Oops, alright, I'll probably look around for a workaround.

You could store the length of the field (in terms) in a second field and
then add a MUST term to the BooleanQuery which is a RangeQuery with an
upper bound that is the maximum length that can match.

Thanks Ian. Also, if I have a unigram in the query, and I want to make sure
I match only index entries that do not have more than 2 tokens, is there a
way to do that too?
Thanks

Hello,
I have a rather simple query. I have a list where I have terms like and
then my query is more natural language. I want to be able to retrieve
matches that has atleast 2 words in common between the query and the index
Can you guys suggest a Query Type and a field that I should be using?
Break the query into words then add them as TermQuery instances as
optional clauses to a BooleanQuery with a call to
setMinimumNumberShouldMatch(2) somewhere along the line. You may want
to do some parsing or analysis on the query terms to avoid problems of
case matching and the like.

Resending, I think this got dropped by the list for some reason

Hi,
It is not a good idea to extract each document. You can be more efficient
by only looking at the fields you are interested in. Depending on the size
of your index, you can try:
String[] codes = FieldCache.DEFAULT.getStrings(indexReader, fieldName);
This returns a string [] with the length
