Subject Re: How to use AND / OR with DismaxRequestHandler?
Date Mon, 02 Jul 2007 12:08:12 GMT
Hi

Take a look at the query parameters it supports:

http://wiki.apache.org/solr/DisMaxRequestHandler

An exact combination (phrase), all of the words or one are possible:
you can use the mm parameter (100% and 1 for your case).

Part of a word is not possible, nor explicit query fields in the q parameter.
