XF 2.1 Restapi and search


Well-known member
Today i took two addons from AndyB and melt them to a new one; now i have a quick-search for posts just for the admin.
It is slow and while i have limited the posts to search for by some criterias i dont like the way it works with finder and posts, but i still have no idea about how to use the search-index. (next thing to do, now)

Now i would like to do the the same search again, but with the API. But i dont find the word "search" or "search index" in the docu.
is there no function to use the search-index with the api?
