Enthuware

I can also tell you that discuss link in question "com.enthuware.ets.scjp.v6.2.25" leads here. That's why there is a "Math.random()<.05? break : continue;" question before. That's also why i knew the answer for this question later
I feel like you should pay me for testing the app

It is just a simple search in the topic field. 2.25 matches with 2.257. It has nothing to do with the app as such. One can create a new topic with the new question id if the search is not a perfect match.

HTH,
Paul.

And as i checked, the "About Question.." beginning is case sensitive in the search

Actually, behind the scenes, it is an Sql like query i.e. where topic like %qid%
