Subject [jira] [Commented] (SOLR-3385) Extended Dismax parser ignores all regular search terms when one search term is using + (dismax behaves differently)
Date Fri, 20 Apr 2012 15:20:42 GMT

    [ https://issues.apache.org/jira/browse/SOLR-3385?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13258304#comment-13258304

Erick Erickson commented on SOLR-3385:
--------------------------------------

Several things:

1> Please discuss issues like this on the user's list before raising a JIRA. I suspect
that this is more an issue for you understanding how dismax works than a problem in the code,
but I'm not sure (see below).

2> Please attach the results of adding &debugQuery=on and show what you think is the
error. That way we can see whether it's a real bug or not. For instance, if you've put the
raw + in the URL, your browser may be transforming them into spaces which would produce the
behavior you're seeing.

> When using the extended dismax parser with at least one term using + or -, all other
search terms are ignored.
> Example:
> (the terms dev and sales are found in the index, the term miau is not part of the index)
> "dev sales miau", "+dev +sales +miau", "dev +sales +miau" all give me 0 results (as expected)
> "dev +sales miau", "dev +sales" or "+sales" return the same number of results (dev and
miau terms are ignored)
> The standard dismax parser always treats search terms as +, so "dev sales miau", "+dev
+sales miau", "dev +sales miau" return the same number of results.
