I think you can build your own plug-in and do whatever type of search you
want(lucene style), I myself added a query plugin to handle my needs ;-).
Cheers,

pattern matching and boolean searches
Posted by Edward Quick <ed...@hotmail.com>.
Hi,
I posted this question the other day but didn't get a reply which may have
been because it was an an annoying FAQ, or the subject wasn't catchy enough!
Anyway, one more try, so here goes! Please help if you can.
Should I be able to do lucene type searches with Nutch? I know Nutch can now
do type: and url: queries, but how about pattern matching queries? For
example:
te*t
tes?t
or Boolean searches? I haven't got it to work so far, but wondered whether
there was some I needed to enable. Incidentally, yes, I did enable the
index-more and query-more plugins.
Thanks for any help.
Ed.

OK, I figured out the part with the bin/nutch server and now the server
is running.
I have created a file /mapred/search-servers.txt
Which contains the line:
localhost:8070
which I'm not sure is what should be there.
In the the WEB-INF/classes/nutch-default.xml I set the value of
searcher.dir to point to /mapred where I have the aforementioned file .
Thanks,
Gal
