Thank you for this report. We have added "ts < <date>" part in the last plugin update and that is good that you found this issue and reported!
Could you please tell me some more information before we develop a fix for this?
- How much records are now in your wpftsi_tp table?
- What is the engine used for this table? MyISAM or InnoDB?
- Could you send me a sample of some records in this table? Just 20-30 records would be fine.
This table should be normally empty and should contain only some rows related to the latest search.
After doing points 1-3 could you also truncate this table (in case there are a lot of records) and tell me if this fixed the performance issue?
After truncating, do this table grows constantly with each new search query request?
Thank you for this report and your help!
