language analyzer not working with span query elasticsearch?

Question

I have an index my_index and a type my_type

{
  "mappings": {
    "my_type": {
      "properties": {
        "my_text": {
          "type": "text",
          "analyzer": "spanish"                 
        }
      }
    }
  }
}

then I want to search for 2 or more words, with, or without gaps but in the specified order.

For that I wrote the following query:

{
  "query": {
    "span_near": {
      "clauses": [
        {
          "span_term": {
            "my_text": "creación"
          }
        },
        {
          "span_term":  {
            "my_text": "fundación"
          }
        }
      ],
      "slop":4,
      "in_order": true
    }
  }    
}

The query is not producing results. But if i search "creacion" and "fundacion" (without diacritics) the query show results. If i do a phrase_query "creación de una fundación" produces results, so i think there is not support for language analyzers in span queries?

Thanks in advance...

Span queries are NOT analyzed, nor stemmed. They are LOW level queries exposed by the API and you need to know how it is stored before u do the SPAN query.
