[basex-talk] Indexes getting removed after update operation in database

Hi, I am using Basex version 8.6.6 i am creating full text indexes on database from the GUI, when any update operation is happening on the database all created indexes getting removed. when i use ft module to search anything then error occurs that database "test" has not full text index. I am expecting if index already created then it should not removed, please suggest how can i resolve this issue. Regards Dharmendra Kumar Singh
