Here is my mapping for a field:  
`"likes": { "type": "text", "fields": { "length": { "type": "token_count", "analyzer": "email_analyzer" } } }, `

likes is an array of email ids, i.e  
likes : ["[a@b.com](mailto:a@b.com)", "[b@c.com](mailto:b@c.com)"]

While searching, i would like to retrieve the "likes.length" field instead of entire likes as likes.length would store size of the array.

I tried with \_source : ["likes.length"] , but its not showing up.

thanks,  
Raja
