Does anyone know of a solution to this problem? I've tried several of
the approaches below but so far also have been unable to search for a
custom field I created. It shows up in Luke just fine but using the
custom field in query strings consistently gives 0 results.

My goal is this: I try to restrict search results to spesific pages

have spesific metadata fields set to known values. So I add a few
checkboxes to the search form in addition to text input so that the
user
can make restrictions for example looking like this
Location
[ ] UK [X] USA
So I used this example
http://wiki.apache.org/nutch/WritingPluginExample-0%2e9
to index the metafields in question. And now when I check with Luke
what
the index looks like it has those fields in place. But my problem
is that
when ever I try to search something and at the sametime restrict
the query
to some spesific location (in this case) I get zero results. The
same goes
when I use only the text input to make a query like this
wordtosearchfor +location:USA
or I when I set programmitcally the loation field in Query object with
addRequiredPhrase("USA","location") or with addRequiredTerm...
I have checked that my queryfilter gets executed in every query and
have
tried to change the class that my filter extends to
RawFieldQueryFilter. I
have even tried to add the location field to default fields in
BasicQueryFilter (I was desperate). I have also tried to change the
way
Lucene indexes the fields I save (stored or no stored, tokenized or
untokenized).
At one point I thought that there was a bug in the field search
feature
but then I noticed that I do get some results with queries like this
wordtosearchfor +url:urlcontainingtheword
and after that I tried to mimic everything that was done to url field
(from parsing to indexing and to querying). But to no avail. Always
zero
results.
I've already spent too much time working on this and I'm obviously
on a
wrong track here :)
Any toughts someone? There propably is a plugin ready that does the
same
thing I try to accomplish here (you can point me to it) but I
really would
like to know what I'm doing wrong.
cheers,
