Subject [Solr Wiki] Trivial Update of "DisMaxQParserPlugin" by JanHoydahl
Date Tue, 15 Feb 2011 16:01:23 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Solr Wiki" for change notification.

The "DisMaxQParserPlugin" page has been changed by JanHoydahl.
The comment on this change is: Changed note about edismax.


  The DisMaxQParserPlugin is designed to process simple user entered phrases (without heavy
syntax) and search for the individual words across several fields using different weighting
(boosts) based on the significance of each field.  Additional options let you influence the
score based on rules specific to each use case (independent of user input).  The DisMax document
has more background on the conceptual origins and behavior.
- '''NOTE:''' Post Solr 1.4 there will be an Extended DisMax parsing that will improve punctuation
handling and relevancy calculations, among other things.  It may be called '''edismax'''.
 See JIRA [[|SOLR-1553]]
+ '''NOTE:''' Solr 3.1 will include an experimental version of the Extended DisMax parsing
that improves punctuation handling and relevancy calculations, boolean operators among other
things. It is called '''edismax'''. See JIRA [[|SOLR-1553]]
