[jira] [Created] (LUCENE-8936) Add SpanishMinimalStemFilter

vinod kumar created LUCENE-8936:
-----------------------------------

             Summary: Add SpanishMinimalStemFilter
                 Key: LUCENE-8936
                 URL: https://issues.apache.org/jira/browse/LUCENE-8936
             Project: Lucene - Core
          Issue Type: Improvement
            Reporter: vinod kumar


SpanishMinimalStemmerFilter is less aggressive stemmer than SpanishLightStemmerFilter

Ex: 
1. camiseta niños -> *camiseta* and *niños*
2. camisas -> camisa

Here *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.
It will preserve gender context with tokens *niños* ,*niñas* *chicos* and *chicas*
