Hi Scott, now your queries are going to be created by a QueryParser. you
have a couple of options here, most common are LuceneQueryParser,
DismaxQueryParser and ExtendedDismaxQueryParser, but there are others. The
QueryParser will be creating all those queries you mentiones, for example,
if you are using the LuceneQueryParser and you send the query string:

field1:foo AND field2:bar

it will create a BooleanQuery with two TermQuery as clauses. The same with
more complex queries.

There are also some other QueryParsers for more specific cases. Take a look
at this class: org.apache.solr.search.QParserPlugin

You can choose and change the query parser with each request.

Local params can also be useful for you:

Regards,

Tomás
