Re: Innodb full table scan if query return 0 rows

I have tried an index (plug, created)
this index speed up the query if there are no data in the specified range, but slow down any other query.
all my query must return data ordered by created field.
the index (plug, created) seem that cannot be used for ordering data, instead index (created, plug) can.

solving one issue will create a new one.
