"textify/OCR" process, then there's no reason to expect it to do better next time. The premise here being that once you've failed each stage in the text extraction a.k.a. This user-observed behaviour has been forcibly stop gapped by me with those "fake words" being injected into the output when, at the end of all the things we tried in that workflow, there still is nothing to report home. The "curious" bit of Qiqqa was (and in ways still is), at least from a user perspective, that it keeps re-trying the text extraction/OCR business an infinite number of runs, when the entire workflow does not succeed in delivering any words for a given page.

there's no sanity check on the mupdf output, which in some very peculiar "obfuscated" PDFs can lead to very interesting results.Īnyway, that's about the list of causes I can come up with, in order of decreasing horribleness.

a page Text Extraction action ("OCR" (but not really 😉 ) via mupdf delivers an empty result where Qiqqa somehow fails to notice (I believe I have covered this possibility in the code already (since the v82 releases), but I keep getting surprised by some very obscure PDFs out there in the wild once in a while, so I am hedging my bet here.a page OCR run by Tesseract where Tesseract fails to deliver anything usable (do note that I do not say legible here, as that is another can of worms for some PDFs).

a page with a full page graphic which has some words in there, but Tesseract still throws out a "no can do" empty or crap result, which will end in the conclusion: "empty page".

the page is a full page graphic (in which case Qiqqa would have been correct not to find any words).

These "faked" words signal that Qiqqa is unable to get some text from that particular page. The QiqqaOCRFailedFakedWord.* "words" are a recent addition of mine as I ran into the same trouble as you and though there's the Qiqqa log output, it was very much unclear what exactly drove Qiqqa (in my case) to retry text extraction + OCR activity for several documents (and particular pages) ad nauseam:

Why does Qiqqa give the reassuring message that "All 8xx pages are searchable, with 0 to go" when it already knows that they are NOT recognized?.

When I browse, why does Qiqqa not place a warning on the defective pages of the document?.

Why did the status line not report these failures?.

Why did Qiqqa need OCR process, when Texification would have sufficed?.

How can we rely on Qiqqa to search within such partially recognized docs? This unpredictability of textification/OCR undermines Qiqqa's dependability! (It is able to select words on other pages that are recognized well.) I checked out these pages, and indeed Qiqqa cannot select individual words with the Text select tool. To my shock, I found that many pages are reported as lost!

So I was under the impression that all was well.īut when I tried the Convert your pdf to text command. (This is another weird feature of Qiqqa: The status line flashes random massages, which disappear after some time. The status line says All 8xx pages are searchable, with 0 to go, with a dark green highlight. So I am assuming that Qiqqa has finally overcome its procrastination and finished all lazy background tasks. This file is lying in Qiqqa for several days now (I have to mention this factor also because Qiqqa has this strange habit to keep tasks pending for days on end.). It is a "pure text" file (no embedded images) which means it requires only textification stage and no OCR stage. The Supreme Court judgment file already contains searchable text (it does not have scanned images).
