---------------------------------------
Hi [~vinod1812],
the patch looks fine. Actually I cannot review the {{SpanishMinimalStemmer}}
class (I don't understand Spanish), but other parts looks okay to me. And this
passed {{ant precommit}} (thanks!).
I will commit it after waiting 24 hours if there are no other comments.
About the github PR, only the Lucene/Solr committers have the write permission
to the apache/lucene-solr repo. So you have to fork the repo and open a pull
request. But this time, a patch has been provided so you do not need to do so.

> SpanishMinimalStemmerFilter is less aggressive stemmer than
> SpanishLightStemmerFilter
> Ex:
> input tokens -> output tokens
> 1. camiseta niños -> *camiseta* and *nino*
> 2. camisas -> camisa
> *camisetas* and *camisas* are t-shirts and shirts respectively.
> Stemming both of the tokens to *camis* will match both tokens and returns
> both t-shirts and shirts for query camisas(shirts).
> SpanishMinimalStemmerFilter will help handling these cases.
> And importantly It will preserve gender context with tokens.
> Ex: *niños* ,*niñas* *chicos* and *chicas* are stemmed to *nino*, *nina*,
> *chico* and *chica*
