Subject [jira] [Commented] (SOLR-3243) eDismax and non-fielded range query
Date Tue, 11 Sep 2012 13:45:07 GMT

    [ https://issues.apache.org/jira/browse/SOLR-3243?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13453021#comment-13453021
] 

Jan Høydahl commented on SOLR-3243:
-----------------------------------

Bill Bell, would you care to test this and comment.

I think there is still a loophole for a bare * query - it gets expanded across all fields
as well and is less efficient than a MatchAllDocsQuery, which is more likely to be the intent
when issuing a *. Perhaps we can incorporate that in this issue as well?

> Reported by Bill Bell in SOLR-3085:
> If you enter a non-fielded open-ended range in the search box, like [* TO *], eDismax
will expand it to all fields:
> {noformat}
> +DisjunctionMaxQuery((content:[* TO *]^2.0 | id:[* TO *]^50.0 | author:[* TO *]^15.0
| meta:[* TO *]^10.0 | name:[* TO *]^20.0))
> {noformat}
> This does not make sense, and a side effect is that range queries for strings are very
expensive, open-ended even more, and you can totally crash the search server by hammering
something like ([* TO *] OR [* TO *] OR [* TO *]) a few times...
