Trying to clean-up Database (is ‘wpftsi_vectors’ needed?)

Hello everyone,

While trying to clean-up my database, I notice I have the following tables that I’m not sure what they are related to. From a few Google searches, it seemes they are related to an internal-search related plugin that was used in the past, but I’m afraid to drop the table in case it’s something that WordPress is using.

• wpftsi_vectors
• wpftsi_rawcache
• wpftsi_docs
• wpftsi_ilog
• wpftsi_index
• wpftsi_tp
• wpftsi_words
• wpftsi_qlog
• wpftsi_map

and a few other similar ones.

I wouldn’t care if other plugins are using this, I would remove them too, I just want to know if this is something that WP needs by default.

Many thanks!
