Hi,
I want to search multiple fields by default (which is no supported by
StandardRequestHandler), but I also want to be able to use Lucene's
boolean syntax (AND/OR/NOT). This doesn't seem to be supported by
DisMaxRequestHandler. I will need to copy or extend
StandardRequestHandler
and modify it, including the query parser it calls, or am I missing an
easier alternative?
You could write your own request handler, but I think the route that
most people take is to stop using lucene query syntax and move to
dismax params to express requirements. This also plays better with
caching.
NOT clauses -> fqs
required clauses (either OR or AND) -> q + mm
purely optional clauses -> bq/bf
If you want complicated (read: parenthesized) boolean logic, it's
best to develop your own solution.
