Chris has given an example of how to perform categorisation of lucene searches:
String[] mfgs = ...;
String query = "+category:cameras +price:[0 to 10]";
Query q = QueryParser.parse(query);
Hits results = searcher.search(q, mySort)
BitSet all = (new QueryFilter(q)).bits(reader)
int[
Can you give me an example of how this might be done?

I believe that this happens because "AND", "OR" and "NOT" are all
reserved words for joining together other search terms and therefore if
you don't want the exception thrown then you must capture any "AND",
"OR" and "NOT"s that are entered on their own and not pass them to the
QueryParser.

Hi all,
I have read that Lucene performs caching of search results so that if
you perform the same search in succession the second result should be
returned faster. What I wanted to ask is whether this caching is any
good or whether it's a good idea to add some sort of caching layer on
top of Luc
that these are the
caches that are built at the first query. So, say storing the results of
a query somewhere and returning that stored copy for the *next* query
that is identical is not something I'd expect Lucene to do.

Hi All,
I want to be able to do a search for a term in all fields in a document.
One way this can be done is to put every element of a document in the
default field (or I guess any other single named field) as well as
separate fields in which those elements belong. So for example if for
my docu

document, so unless you need complex queries, I'd just think about
rewriting simple queries with ANDs as a SpanNearQuery.

Hello,
I was wondering if Lucene provides any mechanism which helps in
pagination. In other words is there a way to return the first 10 of 500
results and then the next 10 and so on.

Having some "special character" in the index doesn't help you because
you still have to specify the field. And your two choices are still
either a BooleanQuery that mentions all fields or indexing the data into
a single field.

See TopDocs, HitCollector, etc. Don't iterate through a Hits objects to
get docs beyond, say, 100 since it's designed to efficiently return the
first 100 documents but re-executes the queries each 100 or so times you
advance to the next document.

Hi all,
A question about efficiency and the internal workings of the Hits class.
When we make a call to IndexSearcher's search method thus:
Hits hits = searcher.Search(query);
Do we actually, physically get back all the results of the query even if
there are 20 million results or for efficiency
What can you use in place of Hits and how do they differ?

Lucene certainly does support it. It just requires you to use a
