Erick Erickson updated SOLR-3017:
---------------------------------
Attachment: SOLR-3017.patch
new version that:
1> removes the new schema file and just modifies schema12 instead. All tests
pass with this change.
2> Adds null check to setStopwordFilterFactoryClass rather than where it's
called.
I guess theoretically someone could override this class, override
setStopwordFilterFactoryClass, call it with null and set the member var to null
then encounter an NPE in noStopwordFilterAnalyzer which they couldn't fix due
to scope issues. But that doesn't sound like something we need to guard against
at this point.
If nobody objects, I'll commit this over the weekend or early next week.
> Allow edismax stopword filter factory implementation to be specified

>
> Currently, the edismax query parser assumes that stopword filtering is being
> done by StopFilter: the removal of the stop filter is performed by looking
> for an instance of 'StopFilterFactory' (hard-coded) within the associated
> field's analysis chain.
> We'd like to be able to use our own stop filters whilst keeping the edismax
> stopword removal goodness. The supplied patch allows the stopword filter
> factory class to be supplied as a param, "stopwordFilterClassName". If no
> value is given, the default (StopFilterFactory) is used.
> Another option I looked into was to extend StopFilterFactory to create our
> own filter. Unfortunately, StopFilterFactory's 'create' method returns
> StopFilter, not TokenStream. StopFilter is also final.
