Subject [Solr Wiki] Update of "DisMax" by HossMan
Date Fri, 30 Jul 2010 01:44:05 GMT
Dear Wiki user,

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

The "DisMax" page has been changed by HossMan.
The comment on this change is: new overview page for concept of "dismax".


New page:
The term “dismax” gets tossed around on the Solr lists frequently, which can be fairly
confusing to new users. It originated as a shorthand name for the DisMaxRequestHandler (which
was named after the !DisjunctionMaxQueryParser, which was named after the !DisjunctionMaxQuery
 class that it uses heavily). 

In recent years, the DisMaxRequestHandler and the StandardRequestHandler were both refactored
into a single SearchHandler class, and now the term “dismax” usually refers to the [[DisMaxQParserPlugin]].

There is a Lucid Imagination Blog post that explains the [[|origins
and conceptual behavior]] of dismax functionality.
