Hazel can't find a word in an OCR'd PDF

Hello
I have a rule to recognize a bank account document :
it must content the word Relevé wich does exist when I am looking for it in the Preview app on osX. But , Hazel still can't find it and then : rule don't match ! The same applies to another rule : with a date in the same rule.
Please note that some of these documents are well read by Hazel, strange no ?
How can it be ?
How to fix it ?
Faithfully, Stef
PS : Im using VUESCAN to PDF and OCR my documents.
