WORD1 blahblah1 WORD1 blahblah2 WORD2

(Note that WORD1 is repeated 2 times, could be more, and that "blahblah" is some random text, always changing, but matched with .*\s*)

The problem is: You want to match when WORD1 is followed at any distance by WORD2, but without any other WORD1 in the way. I mean:

    "WORD1 blahblah2 WORD2" --> match

    "WORD1 blahblah1 WORD1 blahblah2 WORD2" --> not match, although starting also with WORD1 and ending with WORD2,

but it has another WORD1 in the middle.

I tried this pattern (WORD1.*\s*){1}WORD2 as a way to avoid "WORD1 blahblah" repetitions... but doesn't work! Don't know why...

Thanks in advance. 

P.D.: I'll use TRegExpr library
