How to search by Email on Atlas Search

[tomas_ruffa]

Hi all! Im having an issue that I cant find by email using Atlas Search.
This is what I built at the moment:

const suggestedFriends = await this.usersModel
      .aggregate<SuggestedFriends>()
      .search(
         {
           index: 'default',
           wildcard: {
             query: `${friendsQuery.q}*`,
             path: 'email',
             allowAnalyzedField: true,
           },
         }
      )

What im sending on the variable friendsQuery.q is “tomas@gmail.com” but not found nothing. I tried to use another collection that I have names and works properly, I mean the search index its working but not works on strings of emails :/. Someone faced this thing too?

Thank you so much!

Can you share your index definition?

We have an email tokenizer, which helps with this.

Thanks for quickly response here its my index definition

@tomas_ruffa That analyzer won’t work because the lucene.simple analyzer will strip the @ symbol and the . from the email.

In the visual editor, we do not support the custom analyzer you should build to support this use case.

It would look something like this:

{
  "analyzer": "lucene.simple",
  "mappings": {
    "dynamic": true,
    "fields": {
      "email": {
        "analyzer": "emailUrlExtractor",
        "searchAnalyzer": "emailUrlExtractor",
        "type": "string"
      }
    }
  },
  "analyzers": [
    {
      "charFilters": [],
      "name": "emailUrlExtractor",
      "tokenFilters": [
        {
          "type": "lowercase"
        }
      ],
      "tokenizer": {
        "maxTokenLength": 200,
        "type": "uaxUrlEmail"
      }
    }
  ]
}

Thank you so much Marcus I did this and added new refactors to that query by the Atlas UI and now works. Thanks @Elle_Shwer too for the help, both are the solution that I need
