Subject [Solr Wiki] Update of "DisMaxRequestHandler" by JanHoydahl
Date Wed, 30 Jun 2010 21:04:04 GMT
Dear Wiki user,

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

The "DisMaxRequestHandler" page has been changed by JanHoydahl.


  The DisMaxRequestHandler 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)
  '''NOTE:''' As of Solr 1.3, the DisMaxRequestHandler is the exact same thing as the SearchHandler
with the default query parser set to the !DisMax Query Parser (defType=dismax).
+ '''NOTE:''' Please refer to this component as Dismax Query Parser, '''not''' DisMaxRequestHandler
  '''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]]
