I suspect he's running the query through an analyzer that is dropping
out single digit numerics, which would basically be a query that pulls
back everything from the indexes.. or at least I think so.

Sorry, if you have an IN query, it must be BooleanClause.Occur.SHOULD, as
the CategoryID can be 1, or 3 or 7. You query should not match any doc (I
verified this).

I tried
Query q = new BooleanQuery();
((BooleanQuery)q).Add(NumericRangeQuery.NewLongRange("CategoryID", 1, 1,
true, true), BooleanClause.Occur.MUST);
((BooleanQuery)q).Add(NumericRangeQuery.NewLongRange("CategoryID", 3, 3,
true, true), BooleanClause.Occur.MUST);
((BooleanQuery)q).Add(NumericRangeQuery.NewLongRange("CategoryID", 7, 7,
true, true), BooleanClause.Occur.MUST);
But that seems to mach all Documents in my Index.

Have you looked at BooleanQuery? Create individual TermQuery and OR them
using BooleanQuery.

Hi,
I do have some indices where I need to get results based on a fixed
number
list (not a range)
Let's say I have a field named "CategoryID" and I now need all results
where "CategoryID" is 1,3 or 7.
In Lucene 2.4 I created a QueryParser which looked like:
"CategoryID:(1
3
7)". But the Query Parser won't work with NumericFields...
How can I achieve the same for NumericFields?
Btw I'm using Lucene.net.
Thanks for Help
