Assuming you are using Adobe, you can perform Adobe OCR on the scanned PDF to make it editable and searchable: 1. Open PDF in Acrobat X Pro or Acorbat XI Standard 2. Go to ViewToolsRecognize Text in This File 3. You will find the scanned PDF is. To make it text searchable, the best way may be to go back to the original source (e.g. A Word document) and use a different process to produce the PDF. Alternatively you could try rendering your current PDF as a bitmap and then using OCR, but this will be tedious and produce poor results.

Full Text Search of PDF using Adobe Acrobat Lately, everyone’s been asking me to help them find themselves After a talk at the Missouri Solo and Small Firm conference, I chatted with a solo real estate attorney who asked for my advice on developing a searchable article archive from the materials he had collected over the years.

1. Usually, the default search/find commands do not include PDF comments in searches, so be sure to change that setting. In the text search box in Adobe Reader, click the gear settings menu and choose 'Include Comments.' To move away from having text in PDF comments, there is an application included with Adobe Acrobat called PDFMaker.
2. Once Windows has finished indexing your PDFs and their contents, you’ll be able to search for text inside multiple PDF files at once. Use SeekFast To Search PDF Files.

Hi

/game-generator-free.html. I have a standard SharePoint online team site with a document library (in classic mode) that has about 900 pdfs.

If you search by the Name in the Find a File it appears to work just fine but if we try searching for text within the PDF file it returns no results.

Example, inside each of the pdfs there is a field for Assembly/Part # that is filled in with text - trying to search the library with that text never returns a PDF result (it will return Word or Excel results if they have the same text inside them). Searching the entire site also gives no results.

The site Search and offline availability is set to yes, the library's setting for show in search results is yes. There is no approval turned on nor publishing and the users all have at least read access to the entire library and all items within

I have used the Reindex site button and waited 24 hours with the same no results returned
I have reindexed the library and waited 24 hours with no results returned

The defaulty search result source is set to Local SharePoint Results

The PDFs are not scanned - it is a PDF form that the users fill in using Acrobat and then upload to the library.

What am i missing? I've done some research and everywhere it says that this should happen automatically and that as long as it's not a scanned version of the pdf (and therefore an image) SharePoint online should be able to search within a PDF file.

Any insight or help is greatly appreciated!

Thanks,
Stephanie

Problem
I'm trying to determine what type a document is (e.g. pleading, correspondence, subpoena, etc) by searching through its text, preferably using python. All PDFs are searchable, but I haven't found a solution to parsing it with python and applying a script to search it (short of converting it to a text file first, but that could be resource-intensive for n documents).

What I've done so far
I've looked into pypdf, pdfminer, adobe pdf documentation, and any questions here I could find (though none seemed to directly solve this issue). PDFminer seems to have the most potential, but after reading through the documentation I'm not even sure where to begin.

Is there a simple, effective method for reading PDF text, either by page, line, or the entire document? Or any other workarounds?

This is called PDF mining, and is very hard because:

• PDF is a document format designed to be printed, not to be parsed. Inside a PDF document,text is in no particular order (unless order is important for printing), most of the time the original text structure is lost (letters may not be grouped as words and words may not be grouped in sentences, and the order they are placed inthe paper is often random).
• There are tons of software generating PDFs, many are defective.

Tools like PDFminer use heuristics to group letters and words again based on their position in the page. I agree, the interface is pretty low level, but it makes more sense when you knowwhat problem they are trying to solve (in the end, what matters is choosing how close from the neighbors a letter/word/line has to be in order to be considered part of a paragraph).

An expensive alternative (in terms of time/computer power) is generating images for each page and feeding them to OCR, may be worth a try if you have a very good OCR.

So my answer is no, there is no such thing as a simple, effective method for extracting text from PDF files - if your documents have a known structure, you can fine-tune the rules and get good results, but it is always a gambling.

I would really like to be proven wrong.

[update]

Free fonts for illustrator cs6. The answer has not changed but recently I was involved with two projects: one of them is using computer vision in order to extract data from scanned hospital forms. The other extracts data from court records. What I learned is:

1. Computer vision is at reach of mere mortals in 2018. If you have a good sample of already classified documents you can use OpenCV or SciKit-Image in order to extract features and train a machine learning classifier to determine what type a document is.

2. If the PDF you are analyzing is 'searchable', you can get very far extracting all the text using a software like pdftotext and a Bayesian filter (same kind of algorithm used to classify SPAM).

So there is no reliable and effective method for extracting text from PDF files but you may not need one in order to solve the problem at hand (document type classification).

I am totally a green hand, but somehow this script works for me:

I've written extensive systems for the company I work for to convert PDF's into data for processing (invoices, settlements, scanned tickets, etc.), and @Paulo Scardine is correct--there is no completely reliable and easy way to do this. That said, the fastest, most reliable, and least-intensive way is to use pdftotext, part of the xpdf set of tools. This tool will quickly convert searchable PDF's to a text file, which you can read and parse with Python. Hint: Use the -layout argument. And by the way, not all PDF's are searchable, only those that contain text. Some PDF's contain only images with no text at all.

I recently started using ScraperWiki to do what you described.

Here's an example of using ScraperWiki to extract PDF data.

The scraperwiki.pdftoxml() function returns an XML structure.

You can then use BeautifulSoup to parse that into a navigatable tree.

Here's my code for -

This code is going to print a whole, big ugly pile of <text> tags.Each page is separated with a </page>, if that's any consolation.

If you want the content inside the <text> tags, which might include headings wrapped in <b> for example, use line.contents

If you only want each line of text, not including tags, use line.getText()

It's messy, and painful, but this will work for searchable PDF docs. So far I've found this to be accurate, but painful.
