: The book said that dismax query was similar but different to : : DisjunctionMaxQuery
the dismax *parser* in Solr is relatively simple, the majority of the code in it relates to parsing config options, reporting debugging, etc... if you wanted to do something similar in non-Solr java code my personal suggestion would be to just borrow the key ponts of the impl in your own code. : and additionally did Phrase Boosting which I didnt think DisjunctionMaxQuery : did. the crux of the issue is that the "dismax" parser is named after the fact that it heavily uses DisjunctionMaxQuery, constructing one for each "clause" of user input, but things like the phrase boosting and function boosting it supports are just other queries it takes and adds to the top level boolean query it builds. You can find a writeup i did on the concept of the dismax parser at the link below... https://svn.apache.org/viewvc/lucene/dev/trunk/solr/core/src/java/org/apache/solr/search/DisMaxQParser.java?view=markup https://svn.apache.org/viewvc/lucene/dev/trunk/solr/core/src/java/org/apache/solr/util/SolrPluginUtils.java?view=markup https://wiki.apache.org/solr/DisMax http://www.lucidimagination.com/blog/2010/05/23/whats-a-dismax/ -Hoss --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
