no, just ignore that possibly misleading message. As long as the server
is self-aware enough to know it''s the server, and the application does
not think it''s the server, everything is ok :)

Everything is ok, aaf is just a bit noisy :)
you might want to raise the log level for your DRb server to get rid of
these (at some point in time I introduced a configuration option for
ferret_server.yml, not sure if you already have it or not in your
version), or just comment out the relevant line of code that spams the
log this way...

I often find myself doing the same. I go even further - I build
different query variants from the query string the user entered, with a
varying degree of exactness (i.e. exact phrase match, match with
wildcards, fuzzy match), and OR them together with different boosts.
this way more relevant matches are likely to be on top of the result
list because their sub query receives a higher boost, but you also find
matches further away from the original query in case the user had a typo
or so...

lowercase ''in'' should work (in case you also index lowercase
''in'', of
course), imho the reserved words are uppercase only. Or don''t use the
build in query parser but construct your own query objects (which
however might not work with DRb if you build them in your application)
