I am trying to search Exception and results nothing.
It works if I search for the whole string com.xyz.exception.XyzException

Need help.

What is the field mapped as in ES?

Are you using the standard analyzer/tokenizer? I don't believe it is build to split up terms by a period.

If you run this through Sense/Curl I only get one result.
Query:

GET _analyze 
{
  "analyzer" : "standard",
  "text" : "com.xyz.exception.XyzException"
}

Results:

{
  "tokens": [
    {
      "token": "com.xyz.exception.xyzexception",
      "start_offset": 0,
      "end_offset": 30,
      "type": "<ALPHANUM>",
      "position": 0
    }
  ]
}

If you try the same thing for "I am a String" you get:

{
  "tokens": [
    {
      "token": "i",
      "start_offset": 0,
      "end_offset": 1,
      "type": "<ALPHANUM>",
      "position": 0
    },
    {
      "token": "am",
      "start_offset": 2,
      "end_offset": 4,
      "type": "<ALPHANUM>",
      "position": 1
    },
    {
      "token": "a",
      "start_offset": 5,
      "end_offset": 6,
      "type": "<ALPHANUM>",
      "position": 2
    },
    {
      "token": "string",
      "start_offset": 7,
      "end_offset": 13,
      "type": "<ALPHANUM>",
      "position": 3
    }
  ]
}
