David Smiley updated SOLR-758:
------------------------------
Attachment: AdvancedQParserPlugin.java
DisMaxQParserPlugin.java
UserQParser.java
I am contributing source files to this issue instead of patches because the
code was significantly reworked.
Note that this patch depends strongly on SOLR-756 and mildly on SOLR-757 which
I've contributed separately. They need to be applied for this to compile.
Even if you don't get those patches, you can read the source any way to see
what it does.
> Enhance DisMaxQParserPlugin to support full-Solr syntax and to support
> alternate escaping strategies.

> 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...
