Pdf search is not functional at all

I’m facing since purchasing htmlexe that any type of pdf file what so ever coverted via ms office or crystal reports or any type of converter the built in search of htmlexe os not functional.
The company claim that the coverter is the problem.so i tried a pdf file given by htmlexe and build it with htmlexe and i faced same problem.
I send file files and the project file and no one replied.
Anyone has such problem?
