Hello,
Can you please make sure that you have Buddy installed in your Manticore instance?

NOTE: CALL AUTOCOMPLETE and /autocomplete require Manticore Buddy. If it doesn't work, make sure Buddy is installed.

Thank you,
indeed it was manticore buddy, that we installed and all works.

One question, how to LIMIT number of returned results for autocomplete.
For my app i need only 8 results, it seems to returning always random result size.
