Elasticsearch - Filters not working - elasticsearch

Question

I am trying to build a query to return all products of a genre:
curl -XPOST 'http://172.17.0.2:9200/products/_search?pretty' -d '
{
"query" : {
"filtered" : {
"query" : {
"match_all" : {}
},
"filter" : {
"term" : {
"genre" : "Feminino"
}
}
}
}
}'
but the result is zero products. The query doesn't return anything.
If I remove the filter assignment the query works:
curl -XPOST 'http://172.17.0.2:9200/products/_search?pretty' -d '
{
"query" : {
"filtered" : {
"query" : {
"match_all" : {}
}
}
}
}'
The setting of my index are:
curl -s http://172.17.0.2:9200/products/_settings |python -m json.tool

Is there something wrong in my query or in my index?

Answer 1

Resolved.
The problem is the Standard Analyzer.
An analyzer of type standard is built using the Standard Tokenizer with the Standard Token Filter, Lower Case Token Filter, and Stop Token Filter.
https://www.elastic.co/guide/en/elasticsearch/reference/current/analysis-standard-analyzer.html
So, the query:
curl -XPOST 'http://172.17.0.2:9200/products/_search?pretty' -d '
{"query" : {
"filtered" : {
"query" : {
"match_all" : {}
},
"filter" : {
"term" : {
"genre" : "feminino"
}
}
}
}
}'
work very good.
