Subject [jira] [Commented] (SOLR-3145) Velocity /browse GUI should stick to AND as defaultOperator
Date Tue, 13 Mar 2012 17:18:50 GMT

    [ https://issues.apache.org/jira/browse/SOLR-3145?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13228522#comment-13228522

Yonik Seeley commented on SOLR-3145:
------------------------------------

bq.  SOLR-1889 was the correct change [...] Changing the queryparser default to AND is very
bad

+1 (but probably for different reasons than you ;-)

But Jan is talking about just changing the default for just an example GUI (/browse), and
not any query parsers.  That's pretty minor - not a big deal either way, but I do think that
from a "finished product" perspective, more people expect all of their query terms to appear
in matching documents (and I believe this is how google does it?)

> After SOLR-1889 was committed, the DisMax "mm" parameter defaults to whatever set in
q.op. Since defaultOperator in schema.xml is OR, this means that DisMax now defaults to OR
(mm=0) instead of the old default (mm=100%). It should stick to AND as before.
