Another approach...
You can make a Filter that is the inverse of the output from another
filter, which means you can make a QueryFilter on the search, then wrap it
in your inverse Filter.
you can't execute a query on a filter without having a Query object, but
you can just apply the Filter
Thanks for everyone who has been posting possible solutions. I am making
great progress and learning a lot.
This works, but the results include files that don't even contain a
kcfileupload field (not good):
query1 = QueryParser.parse(jpg, kcfileupload, new StandardAnalyzer());
query2 =
Hello;
I think Chris's approach might be helpfull, but I can't seems to get it to
work.
So since I running out of time and I still need to figure out starts with
and ends with queries, I have implemented a hacky solution to getting all
documents with a kcfileupload field present that does not
Alternatively, add a dummy field-value to all documents, like
doc.add(Field.Keyword(foo, bar))
Waste of space, but allows you to perform negated queries.

Ok.
I have added the following to every document:
doc.add(Field.UnIndexed(olFaithfull, stillHere));
The plan is a query that says: olFaithull = stillHere and kcfileupload!=jpg.
I have been experimenting with the MultiFieldQueryParser, this is not
working out for me. From a syntax how is this
Hello,
Still working on the same query, here is the code I am currently working
with.
I am thinking this should bring up all the documents that have
olFaithFull=stillHere and kcfileupload!=jpg (so anything else)
query1 = QueryParser.parse(jpg, kcfileupload, new StandardAnalyzer());
query2 =
-kcfileupload:jpg +olFaithFull:stillhere
This looks right to me. Why the 0 results?
Looks good to me, too. You sure all your documents have
olFaithFull:stillhere and there is at least a document with kcfileupload not
being jpg?

Yes. There should be 119 with stillHere, and if I run a query in Luke on
kcfileupload = ppt, it returns one result. I am thinking I should at least
get this result back with: -kcfileupload:jpg +olFaithFull:stillhere?

You have double-checked that, haven't you? :)

You really should.

I did, I have ran both queries in Luke.
kcfileupload:ppt
returns 1
olFaithfull:stillhere
returns 119

First thing that jumps out is case-sensitivity. Does your olFaithFull
field contain stillHere or stillhere?

First thing that jumps
Because you are build from QueryParser rather than a TermQuery, all
search terms in the query are being lowercased by StandardAnalyzer.
So your query of olFaithFull:stillhere requires that there is an exact
index term of stillhere in that field. It depends on how you built
the index (index and
Bingo! Nice catch. That was it. Made everything lower case when I set the
field. Works great now.
Thanks!
