+Configs/SearchSystemTitle/Description: There are a large number of system titles in the wiki that make up the Tiddlywiki operating system, and searching for them can be slow. Check this option if you are one of Tiddlywiki's developers and often search for system titles. (only involves free searching of system tiddlers, so you can search layouts, system actions, etc. without checking this option)

-Configs/CacheSystemTiddlers/Description: Assumed system tiddlers don't change during wiki usage, so they are only loaded to the front-end cache once for the initial search, and then no longer loaded with the latest data for subsequent searches. Note that this option includes all results from searches done with {{$:/plugins/linonetwo/commandpalette/commands/help/System!!command-palette-prefix}}.

 Configs/MissingFilterOnTop/Description: When checked, when using `[` filter search mode, if there is no matching filter, it will be displayed on top, so that you can directly use the new filter you just entered to search. When unchecked, it will be at the bottom, so that you can search for the filter tiddlers tagged with `$:/tags/Filter`.
