How about a BooleanQuery? I have documents with text, headlines, and
keywords, each needing a different analyzer and boost factor. I'm
experimenting with PerFieldAnalyzerWrapper and KeywordAnalyzer (as
described in your book), constructing the Query from a
QueryParser.parse(query, field, analyzer) query on each of the fields,
connected as a BooleanQuery. Like this, i can use a different boost
factor
and a different analyzer for each field, and tune the whole thing
quite
easily. The drawback is that analyzer and query construction look a
little
cumbersome.
As i said, i've been only experimenting with this. I don't know if
this
would work in production code, but i don't see why not. What's your
take
on this?
That's a perfectly good approach as well. I didn't mean to imply
that there were only "two options", just that the two I suggested
were the most commonly used ones.
