does visual filters need doc notebooks to store visual search info like other Highlighting?
No - at least if I understand you correctly.
They are defined in Visual filter documents as outlined in https://support.logos.com/hc/en-us/articles/360016747431-Create-a-Visual-Filter
i check out wiki page, that is good i have to many documents already, i wish there was a way to delete docs permanent off our Faithlife account webpage

What problem is these documents persisting causing you? I will admit I rarely think about those documents that are in the "trash" - but it is very helpful if I want to restore any that I deleted in error.
i think its a waste when you do a test run
I don't understand. What kind of test can you run that uses them?
and found out you can get lot done in bible with visual filter instead of making many notes.
Those deleted public documents will not affect the performance of your Logos in any way. They are no longer among you available documents they merely exist in the backup cloud accessible only for purposes of restoration not directly to Logos.
