ecaradec, i'll split your question off into another thread after i answer it a bit.
we should probably have sdk questions as their own threads, but titled so they can be identified as such (e.g. "SDK Question: blah blah")
ok now to your question..
i'm not 100% sure what you are asking, could you be a bit more specific?
maybe it will help if i explain a little bit about how farr works with plugins and results.
before farr does any searching of it's own it calls the plugins and tells them the search.
then it checks if any plugins have results right away, and if they want farr to stop searching immediately.
most plugins respond at this point since they can return results without delay, and normal farr searching never proceeds.
but some plugins may need an extended time to search, and may want farr itself to be able to proceed and find files on its own. for example if you had a plugin that searched online or and index, BUT still wanted normal results displayed. in this case a plugin can let farr continue searching while it works, and send results as ready.
but again, i'm not 100% sure what you are saying works faster than what.
