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.
> Extended Dismax parser ignores all regular search terms when one search term
> is using + (dismax behaves differently)

> Key: SOLR-3385
> URL: https://issues.apache.org/jira/browse/SOLR-3385
> Project: Solr
> Issue Type: Bug
> Components: query parsers
> Affects Versions: 3.5
> Reporter: Nils Kaiser
>
> 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.
