Elasticsearch won't index single characters

Hi everybody,

I'm facing a strange issue with Elasticsearch x Sugar.

Some of the Accounts created with the following names are not returned when typing their names in the quick search. For example : 

  • C For Clean
  • C & D - associés
  • Architectes Atelier D & R
  • AC Kayl

When there is a single character, the search result won't return the string filled in the input.

Do you have an idea ?

Sugar is running on 11.0.3 PRO.

Thanks in advance for your ideas.

Best regards,

Enes
