[Solr Wiki] Update of "DisMaxQParserPlugin" by JanHoydahl
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:
http://wiki.apache.org/solr/DisMaxQParserPlugin?action=diff&rev1=8&rev2=9
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:''' 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 [[http://issues.apache.org/jira/browse/SOLR-1553|SOLR-1553]]
+ '''NOTE:''' From [[Solr3.1]] a more advanced parser called ExtendedDisMax is available, improving punctuation handling, relevancy calculations, full query syntax, aliasing among other things. It is registered in the example config as '''edismax'''.
