> 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.
