Mike Sokolov created SOLR-6842:
----------------------------------
Summary: distinct field list for quoted phrases in edismax
Key: SOLR-6842
URL: https://issues.apache.org/jira/browse/SOLR-6842
Project: Solr
Issue Type: Improvement
Components: query parsers
Reporter: Mike Sokolov
As a user, I'd like to be able to specify more precise term-matching by
surrounding a term with double quotes. To support this, we need to be able to
supply a different set of fields for phrases than for bare terms. Specifically,
we'd like to treat phrases as more "exact" - probably turning off stemming and
generally having a tighter analysis chain.
I have a working implementation now that is a quite small, built as an
extension of ExtendedDismaxQParser and friends. If there's interest, I can do
the work to merge the small changes in with the existing classes. Basically my
idea was to create a parallel set of Aliases for a dummy default phrase-field
(named IMPOSSIBLE_PHRASE_FIELD_NAME), and then to use that for user-supplied
phrases when there are aliases present, instead of the current default. I
would propose to name the new field "pqf" - - "phrase query fields", by analogy
to "qf". Existing code is here:
