Effective e-mail or URL link search inside text

Let's search in the content field of the documents that we have for the e-mail address <[e-mail]>:

{
  "query" : {

      "content" : "[e-mail]"
      }
    }
}

Let's see why this happened and how:

• The standard analyzer breaks <[e-mail]> into malhotra and gmail.com

The solution for this problem is to use the UAX Email URL tokenizer rather than the default tokenizer. This tokenizer preserves...
