Subject: solr to handle special charater

...the docs for dismax said that + or - followed by nonwhitespace characters had special meaning ... for some reason i thought the dismaxhandler had code that would look for things like "xyz - abc" and autoescape it to "xyz - abc" (after calling partialEscape) so that the +/- would only be special if the were treu prefix operators.

apparently this never actually existed.

we should figure out if that's how it should work, and if so implement it.

this would also be a good time to make the autoescaping behavior of dismax more configurable, or at least more overridable by subclasses (it's currently handled by a static method call)
