Keyword Search does not find words or expressions inside the candidate's resumes

Hi,

I enabled the advanced candidate search in our pod. The Keyword Search works very well and allows to find keywords or boolean expressions inside the candidates profiles. However I noticed that the Keyword search cannot find words or expressions inside the candidate attachments (resumes or cover letters).
I attached the screenshots "Candidate_Search_1.png", "Candidate_Search_2.png" and "Candidate_Search_3.png" where I showed you that entering an expression in the Keyword Search which has been taken from a candidate resume I do not obtain any result. The same behavior is shown for every expression taken from a candidate attachment regardless of the attachment format.
