Brief result I brought about? Far from it (12)

I believe the answer is:

filibusterer

I'm a little stuck... Click here to teach me more about this clue!

'far from it' is the definition.
I can't judge whether this definition defines the answer.

'brief result i brought about?' is the wordplay.
'brought about?' is an anagram indicator (I've seen 'brought about' mean this).
'brief'+'result'+'i'='briefresulti'
'briefresulti' with letters rearranged gives 'FILIBUSTERER'.

Can you help me to learn more?

(Another definition for filibusterer that I've seen is " One speaking at length to block legislation".)

I've seen this clue in The Times.
