The problem is that OCR'ed PDF documents are often difficult to parse, and the result depends on the method used. You often get different results when you open the document in Adobe Reader, in Preview, when you search using Spotlight etc, because sometimes some spaces are dropped between two words, and some other times, spaces are inserted inside a word. For example, the "this is an example" string can be parsed as "thisisanexample", or as "t h i s i s a n e x a m p l e".
To see how a document content has been parsed, you can option-click the document in FoxTrot's result list.
By default, the current version of FoxTrot uses the Xpdf engine to parse PDF documents, that's why the result is different than when you search using Spotlight. You can make FoxTrot use the Spotlight importer instead of Xpdf, and in fact with recent versions of OS X, you will generally get better results. FoxTrot 5.1 will use the Spotlight PDF importer by default.
To change this setting, press the command and option keys while launching FoxTrot, check "Manage third-party metadata importers", then uncheck "Prefer Xpdf for PDF documents". You will have to rebuild your index for the change to apply on already indexed documents.

"FoxTrot is the one app with which I would have to go back to the PC
because Spotlight is so profoundly useless for serious research (don't
get me started). FoxTrot steps in and does about everything I need to
and does it quickly and with grace. Everytime I have emailed the devs,
I get a timely and responsive answer. I have a few quibbles of course
such as the use of non-standard Boolean operators (| instead of OR for
example) but overall I am very, very pleased.
Believe me, I am a serous researcher and this is what you want!"
