Cassandra Targett closed SOLR-3385.
-----------------------------------
> Extended Dismax parser ignores all regular search terms when one search term

> 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.
