Hi,

I have setup a custom analyzer with uax\_url\_email as tokenizer. I have  
added a pattern\_capture filter to index the emails.  
Now I would like that the urls be searchable and I would like to do the  
same but executing the filter with a condition: either if the token starts  
with http or on the specific type of the token URL.  
I don;t know if it is possible and if say, please let me know how to  
achieve it.

Thanks in advance!  
Stephanie

```
    analysis: {
      filter: {
        email: {
           type: "pattern_capture",
           preserve_original: 1,
           patterns: [
              "([\\w\\-\\+\\.]+?)(?:[\\.\\-_](\\w+))?@([\\w\\-]+)\."
           ]
        },
        url: {
           type: "pattern_capture",
           token_type: "URL",
           preserve_original: 1,
           patterns: [
              "(?:(\w+)(?:.|\/))"
           ]
        }
      },
      analyzer: {
        default: {
          type: 'custom',
          char_filter: [
            'html_strip'
          ],
          tokenizer: 'uax_url_email',
          filter: [
            'email',
            'url',
            'asciifolding',
            'lowercase'
          ]
        }
      }
    }

```
