Answer 1

Somehow snowball is not working for me... am getting errors like I mentioned in the comment to @imotov's answer. I used porter stem and it worked perfectly for me. This is the config I used:

curl -XPUT localhost:9200/index_name -d '
{
"settings" : {
    "analysis" : {
        "analyzer" : {
            "stem" : {
                "tokenizer" : "standard",
                "filter" : ["standard", "lowercase", "stop", "porter_stem"]
            }
        }
    }
},
"mappings" : {
    "index_type_1" : {
        "dynamic" : true,
        "properties" : {
            "field1" : {
                "type" : "string",
                "analyzer" : "stem"
            },
            "field2" : {
                "type" : "string",
                "analyzer" : "stem"
            }
         }
      }
   }
}'
