[jira] Updated: (LUCENE-1424) Add ConstantScorePrefixQuery and
ConstantScoreWildcardQuery
[ https://issues.apache.org/jira/browse/LUCENE-1424?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Mark Miller updated LUCENE-1424:
--------------------------------
Attachment: LUCENE-1424.patch
Heres an early review patch.
I switched range and prefix to use multiterm query, but its debatable if thats necessary. Prob a few clock cycles slower, and the benefits are slim beyond overall code design niceness (which counts a lot to me <g>). Just not sure every mutlitermquery would want to have to implement a constantscore version, and the amount of code reuse saved is low (it could do a bit more with something like getFilteredEnum, but thats not much either).
TODO:
look over
some comments maybe
some tests for the constant score versions
rangequery is not as expressive as constantscorequery, which can have separate inclusive/exclusive ends.
When I was talking about deprecating constantscorequery being awkward, its wasnt really in the implementation sense (i think we can leave it as is), but more the deprecating one of the newest queries already :) Still don't consider that a huge deal though.

> If we want to be able to highlight these queries, they need to be added to Lucene core or contrib (solr's WildCardFilter can be used to create the ConstantScoreWildcardQuery). They are very useful anyway.
