I had to edit DateQueryFilter.java (in
src/plugin/query-more/src/java/org/apache/nutch/searcher/more/DateQueryFilter.java)
in order to have queries that just had date by itself.
The relevant line is:
rangeQuery.setBoost(0.0f); // trigger filterization
I changed 0.0f to 1.0f
More generally, I learned that it doesn't matter if a query works in Lucene,
there has to be support for it somewhere in Nutch query code.
I made the same change to TypeQueryFilter.java.
I also added a TitleQueryFilter since I found that there wasn't even any
code for it. All I did was take URLQueryFilter.java and replace
super("url"); with super("title");
HTH.

I am unable to query fields in my index in the method that has been
suggested. I used Luke to examine my index and the following field types
exist:
anchor, boost, content, contentLength, date, digest, host, lastModified,
primaryType, segment, site, subType, title, type, url
However, when I do a search using one of the fields, followed by a
colon, an incorrect result is returned. I used Luke to find the top term
in the date field which is '20060801'. I then searched using the
following query:
date: 20060801
Unfortunately, nothing was returned. The correct plugins are enabled,
here is an excerpt from my nutch-site.xml:

In any case you need at least include the nutch-extensionpoints plugin.
By
default Nutch includes crawling just HTML and plain text via HTTP,
and basic indexing and search plugins.

Any ideas? I'm not the only one having the same problem, I saw an
earlier mailing list post but couldn't find any resolve... Thanks,
Matt
