> The DisMaxQParserPlugin has a variety of nice features; chief among them is
> that is uses the DisjunctionMaxQueryParser. However it imposes limitations
> on the syntax.
> I've enhanced the DisMax QParser plugin to use a pluggable query string
> re-writer (via subclass extension) instead of hard-coding the logic currently
> embedded within it (i.e. the escape nearly everything logic). Additionally,
> I've made this QParser have a notion of a "simple" syntax (the default) or
> non-simple in which case some of the logic in this QParser doesn't occur
> because it's irrelevant (phrase boosting and min-should-max in particular).
> As part of my work I significantly moved the code around to make it clearer
> and more extensible. I also chose to rename it to suggest it's role as a
> parser for user queries.
> Attachment to follow...
