The current PDFE text extraction routines are very weak, alpha stage, and for some pdf's can not extract text correctly. You can check that using the "text viewer" in PDF View mode. Obvious I'm going to try to improve the text extraction in upcoming versions, but right now I�m focusing my coding time doing other improvements.

Also note that the best way to search for text content is to use the DBSearch scan mode, IndexedContents option, after index the pdf's text using the IndexTextWords batch tool. You are not going to increase the text extraction accuracy, but speed up subsequent full text search operations.

The best way to search for pdf is, after spending some time in QuickInfoEdit mode (Edit>QuickInfoEdit) entering meaningfull information into pdf Infofields, to use the DBSearch scan mode, InfoFields mode. You get search results more fast and more accurate.
