False reporting of "does not contain" with :"e" as a parameter on PC based system

Hi:
In an attempt to locate all unindexed pdf files in my library I found that when I search for 'e' as a does not contain parameter it is reporting some pdf files with plenty of 'e' in the text? I have dutifully re-indexed them but the problem persists. Any ideas why?
Thanks
