Tried using Search topic on 3 threads

Honda Civic 10th gen 800+ pages
Toyota Vios 250+ page
Toyota Yaris 18 page

using the search topic function and pops out either old (circa before march) or not existant in the Yaris thread


is there a time frame on how recent the search applies to the thread

some words will show up more recent post
but words like "bumper" can skip from today, and the next will be march 2020


is this normal?

Initially I thought having pages gone till 800plus or 16k plus post, have done some wonky stuff to the post
(I remember Se7en using mh370 post to try push the limits of post per thread, inn, there is issue when post gone to high)

Then I try using Yaris ,since it's only 18 pages
Tried guarantee and mark on that

Cause I can see the word in post on yesterday and Aug 4 respectively

But it will show no results
