Hello everyone, I would like to ask for some help with a text search. I have some long PDF files in which I would like to search for words. Is there a way to export the places/rows results of the search? I would like to see which page/row the results are on. For example, the text I searched for text (like volvo). And the results will be listed on a different page where I can see which rows of the documents contains that word „volvo” (e.g.: 2. page, 5. page, 13. page etc.) Thank you for instance! Tamas ---

There is no easy way to do that (which I know), but why would you want to do this? Are you trying to see the context in which the word Volvo was used for instance? You could do that with a context window. See the challenge 38 of Just KNIME It to do so. > [@Solutions to "Just KNIME It!" Challenge 38](https://forum.knime.com/t/solutions-to-just-knime-it-challenge-38/48048/6): > > Hi everyone, here is my solution. It only finds the first instance of the lookup word. I also share component named “Word Window” on hub. Lookup word and window length can be configured from component. If you want general information on how to extract from a PDF here is the webinar I ran in August: > [@Webinar: PDF Text Extraction using KNIME, Regex, and Python- August 17, 2022](https://forum.knime.com/t/webinar-pdf-text-extraction-using-knime-regex-and-python-august-17-2022/46049): > > Join @victor_palacios for the webinar " PDF Text Extraction using KNIME, Regex, and Python" on Wednesday, August 17 at 5 PM - 6 PM UTC +2 (Berlin) which is 10 AM - 11 PM UTC -5 (Chicago) [HERE IS THE RECORDING](https://knime.wistia.com/medias/30jiddrbwd)[PDF Extraction Webinar Slides](https://forum.knime.com/uploads/short-url/qt7ZHAlYYZutIxXaLwvHawX6DSg.pptx) In this webinar, we will parse PDF documents using the no-code, free tool KNIME and integrate it with code-based tools - Regex and Python.

@janszky_nav I adapted an older example ([How to read multiple lines from PDF File - #6 by mlauber71](https://forum.knime.com/t/how-to-read-multiple-lines-from-pdf-file/46510/6)) using R code to extract the text from PDF files and then search for the page and line where a special word (in this case “Procter”) would appear. ![image](https://forum-cdn.knime.com/uploads/default/original/3X/5/8/587bf806b673fdb2846ab502e64519d597c173f9.png) ![image](https://forum-cdn.knime.com/uploads/default/original/3X/9/d/9dc12dbd91f23a8f5a1eab8a93fe95c1b5c9e5de.png) > **[use R and KNIME to extract text from PDF file - search for page where text...](https://hub.knime.com/mlauber71/spaces/Public/kn_example_r_pdf_read_text~NCmYaa3cn4lEHyUR/current-state)** > > use R and KNIME to extract text from PDF file - search for page where text appears – Edit: [KNIME — Extract Text and Tables from PDF Files with Python in a Low-Code Environment | by Markus Lauber | Low Code for Data Science | Medium](https://medium.com/low-code-for-advanced-data-science/knime-extract-text-and-tables-from-pdf-files-with-python-in-a-low-code-environment-e2949a95e3fc) ---

I want to do some string manipulation not word embeddings or other text-processing. I just made it up for the challenge like a small lab for string, characters, punctuation and word manipulation etc., 🙂 Thanks for the webinar info. ---

Dear Victor, Thank you for your answer, it was very usful, and I saw the Webinar too. Thank you. May I have one more question? If I have some pdf-s like the sample and I would like to extract text message/call data such as numbers and text. The call text is located before the text **“A jogosult ügy…”**. Whic one cell splitter the best option? Thank you.

I would target the phrase “A jogosult ugy” and then extract 20-30 characters (or more) after it. Then get the data you want from that window. Unfortunately, the data in the txt file seems corrupted? ![Screen Shot 2022-10-27 at 9.23.58 AM](https://forum-cdn.knime.com/uploads/default/original/3X/3/0/300bd64f6617abe5cc74b00c3cd7f20c01f5164a.png) To do the window targeting, I would use Regex. Here is my cheat sheet for Regex: > **[Various Examples of Regex in KNIME – victor\_palacios](https://hub.knime.com/victor_palacios/spaces/Public/latest/Various%20Examples%20of%20Regex%20in%20KNIME~J1anMyaS7MMiRV29)** > > Solutions for data science: find workflows, nodes and components, and collaborate in spaces. Here is what you can use to target that text and extract words after it: ![Screen Shot 2022-10-27 at 9.25.56 AM](https://forum-cdn.knime.com/uploads/default/original/3X/1/e/1e1442e15bacc9450736e650aeef068b85f129cc.png) Finally, challenge 38 from Just KNIME It! may help you accomplish the same task. ---

No, it isn’t corrupted. It is a pdf, i simply change the file extension. (pdf-\>txt) ---
