Jan Høydahl updated SOLR-2792:
------------------------------
Attachment: SOLR-2792.patch
First attempt on patch. It works, and I added an -i option to the command-line
version of HunspellStemmer so that we can test ignoreCase easily.
I also added an optional ignoreCaseLocale to specify the locale for
lowercasing, but this only works for String#toLowerCase, while the lowercasing
in CharArrayMap#equals uses plain Character#toLowerCase.
> Allow case insensitive Hunspell stemming

> Hunspell dictionaries are by nature case sensitive. The Hunspell stemmer thus
> needs an option to allow case insensitive matching of the dictionaries.
> Imagine a query for "microsofts". It will never be stemmed to the dictionary
> word "Microsoft" because of the case difference. This problem cannot be fixed
> by putting LowercaseFilter before Hunspell.
