Aggregations and special characters

Elastic Stack Elasticsearch
1

I am performing an terms aggregation on a query to return the unique values
of a field, in this case the field being emails in the format
example@gmail.com or example@aaa.example.com.

"aggregations": {
"users_overall": {
"terms": {
"field": "email"
}
}
}
Instead of receiving back the full unique emails that I need I get results
such as these:

  • {
  • {
  • {
  • {
  • {
  • {
  • {
  • I've run into this problem with other fields that have values with
    special characters in them as well, is there any way to perform an
    aggregation like this that can ignore the special characters and return the
    full value?

Aggregations work on the tokens for the specified field. These tokens are
generated when a tokenizer is applied to a field. In your case, you do not
want the field to be tokenized at all, so you would either need to define
is as not_analyzed or use a keyword tokenizer, which does not separate
tokens.

Cheers,

Ivan
