Nested filter query issue

Hi All,
I am working on nested filter query.But this query is searching only on
nested object properties of type int ,double,date.But not searching when
the properties of string type.
My document structure is given below-

"sectionResults": [
{
"SectionName": "Project Details",
"itemResults": [
{
"InspectionItem": "Project Id",

               "Value": "asd",
               "NumericValue": 0,
               "DoubleValue": 1,
               "LongValue": 0,
               "DateValue": "2014-10-08T00:00:00"
           }

        ]

   }

]

and my query is -

{

"query": {

"filtered": {

  "query": {

    "match_all": {}

  },

  "filter": {

    "nested": {

      "path": "sectionResults.itemResults",

      "filter": {

        "bool": {

          "must": [ 

            {

              "range": {

                "sectionResults.itemResults.DateValue": {

                  "from": "2014-10-01",

                  "to": "2014-10-08"

                }

              }

            },

            {

              "term": {

                "sectionResults.itemResults.InspectionItem": "Project Id"

              }

            }

          ]

        }

      },

      "_cache": true

    }

    }

  }

}

}

For Example - If i do search on InspectionItem Property of itemResults.then result found is 0.But gives reults in case of DateValue,DoubleValue properties of object itemResults .Please help.

Thanks in advance,
