Okay - am I confused by what this mod actually does, or is there an error?

When searching does this

a)
1. Display All Posts - shows every post that has the word
2. Display Last Posts - shows just the last post in any thread that contains the word
3. Display Main Posts - shows the first post in any thread that contains the word

or

b)
1. Display All Posts - shows every post that has the word
2. Display Last Posts - shows only the last post if that last post actually has the word in it.
3. Display Main Posts - shows only the first post if that first post actually has the word in it.

I assumed it was a) but it seems to be b) as I am getting some threads showing in the results on one option and not on another.

Could you clarify this for me.

Thanks
