我正在尝试构建一个查询以返回某个类型的所有产品：
curl -XPOST 'http://172.17.0.2:9200/products/_search?pretty' -d '
{
"query" : {
"filtered" : {
"query" : {
"match_all" : {}
},
"filter" : {
"term" : {
"genre" : "Feminino"
}
}
}
}
}'
但结果是零产品。查询不返回任何内容。 如果我删除了过滤器分配，则查询有效：
curl -XPOST 'http://172.17.0.2:9200/products/_search?pretty' -d '
{
"query" : {
"filtered" : {
"query" : {
"match_all" : {}
}
}
}
}'
我的索引设置为：
curl -s http://172.17.0.2:9200/products/_settings |python -m json.tool

我的查询或索引中是否有错误？
编辑：没有过滤器的搜索输出：

解决。
问题是标准分析仪。
使用带有标准令牌过滤器的标准令牌器，小写令牌过滤器和停止令牌过滤器构建标准型分析器。

所以，查询：
curl -XPOST 'http://172.17.0.2:9200/products/_search?pretty' -d '
{"query" : {
"filtered" : {
"query" : {
"match_all" : {}
},
"filter" : {
"term" : {
"genre" : "feminino"
}
}
}
} }＆＃39;
工作得非常好。
