In my case, for any non-trivial search, I always build a boolean query
with relevant parsing for each field, where applicable using something
like oal.queryparser.classic.QueryParser.
So if I had some free text docs with a date field, the latter stored
as you suggest, and a query along the lines of datefrom: 2010-01-01
dateto: 2014-12-31 words: whatever, passed to my app by whatever
means, I'd parse the date fields into a NumericRangeQuery, pass the
words through a lucene supplied parser, getting back some Query
object, then glue them all in to a BooleanQuery with the relevant
MUST/SHOULD logic and boosts and whatever else I wanted.
