Should there be a separate issue to update doc for the query parser(s) beyond
Lucene (I see that Lucene Query Parser is updated)?
{quote}
All queryparsers were updated. But ClassicQueryParser (the lucene one) is the
only one that really
documents its syntax though, so thats where the doc update occurred.
The rest of the QPs mostly re-use ClassicQueryParser's syntax and don't
document any different syntax.
Seriously (unrelated) if you have javadocs for that queryparser module, in
general (especially classes with no javadocs at all!!!!) just throw them up
whereever, email list, this issue, some new issue, I dont care. Ill commit them.

> Edit distance 1 and 2 are now very very fast compared to 3.x (100X-200X
> faster) ... but edit distance 3 will fallback to the super-slow scan all
> terms in 3.x, which is not graceful degradation.
> Not sure how to fix it ... mabye we have a SlowFuzzyQuery? And FuzzyQuery
> throws exc if you try to ask it to be slow? Or, we add boolean (off by
> default) that you must turn on to allow slow one..?
