Subject [jira] [Updated] (SOLR-2996) make "q=*" not suck in the lucene and edismax parsers
Date Fri, 30 Dec 2011 23:18:30 GMT

     [ https://issues.apache.org/jira/browse/SOLR-2996?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Hoss Man updated SOLR-2996:
---------------------------

    Description: 
More then a few users have gotten burned by thinking that "{{\*}}" is the appropriate syntax
for "match all docs" when what it really does (unless i'm mistaken) is create a prefix query
on the default search field using a blank string as the prefix.

since it seems very unlikely that anyone has a genuine usecase for making a prefix query with
a blank prefix, we should change the default behavior of the LuceneQParser and EDismaxQParsers
(and any other Qparsers that respect {{\*:\*}} if i'm forgetting them) to treat this situation
the same as {{\*:\*}}.  we can offer a (local)param to force the old behavior if someone really
wants it.
