there is a search, yes. but it's not working as good (and simple) as the search in VsCode...
Just an example... search for "Scrolling speed" and you won't get any result.
But if you click on "Mouse" in the left navigation you will find indeed a setting "Scrolling speed".
Same for "Lock Screen" > "Show message when locked".
Many settings will just not be found.
Other settings will be found but the search result label is weird.
For example if you search for "position" to change the "Dock position", you will indeed find "Dock settings" as a search result. But it's not "Dock position" so you could assume that there is no position setting existing. This is inconsistent to other search results, i.e. "Highlight colour" will produce a much better search result "Highlight colour - Appearance".
