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