Filtering performed both in search and draw

[kkopachev]

Hi!

I've being profiling search functionality and it came in view that when doing dt.column(0).search(...).draw() DT runs filtering twice. First time when search is called, then second time with draw. That looks a bit weird. I might not understand if there is any underlying reasons that covers, but it looks like a bug. From my understanding, search to be actually output to UI need to be finished with draw call, thus I have question is there a need to perform actual search twice? In case I chain up multiple search calls and finish that with draw call, then I'll get multiple passes. Searches are not identical, however. The difference is in 3rd parameter (iForce) passed into _fnFilterComplete.

Is this real issue? Am I missing something?

I haven't had a chance to look into it yet - but it sounds like it might be a bug. Only on draw should it do the filter. I'll look into it and reply back when I can.

Its 4 years and counting and no reply. Has this issue been resolved?

[DataTables]

Its not no - its slipped by me as I've been working on other things. Its still here though, and anyone is welcome to pick it up if they like. It is something I will look into when I can - things are just busy :-).

Can you refer me to the section of code.

I can't be sure where the problem actually is, but there is where I would start: https://github.com/DataTables/DataTablesSrc/blob/941a2f037381bcd19e64f08c1bb766fc20497373/js/core/core.draw.js#L461 .
