Re: Deadlock from a single query locking the same index twice

The main clue is
... index `word_account_date` ... lock_mode X locks gap before rec insert intention waiting ...

That index is on (word, companyid, datetime). The INSERT is probably going next to a row that the UPDATE is modifying. (Note: "gap")

Probably your best bet is to catch the error, make sure it is a deadlock rollback, and then redo the instruction.
