Hi, I need to extract data regarding: 1. Specifications 2. Typical Properties 3. Technical Features 4. Application from attached documents as examples: [ACURE-500\_EN\_A4.pdf](https://forum.uipath.com/uploads/short-url/sRsGZwvfyAVmXHvgv3y4tp0Rasg.pdf) (198.6 KB) [ACURE-510-100\_EN\_A4.pdf](https://forum.uipath.com/uploads/short-url/aNBIeQf3q2JAegMIT0D7GSrLh3f.pdf) (194.1 KB) [ACURE-510-170\_EN\_A4.pdf](https://forum.uipath.com/uploads/short-url/hZJevgIBVgx4A46niNyeeAntSR0.pdf) (195.4 KB) The middle of the document is set in two columns. Sometimes there is only text to be extracted, another time a table. The content ad 1-4 (as anchors) varies in length. How can I do it with UiPath? I have already tried using Intelligent Form Extractor, but don’t find the functionality to support it. Am I using it wrong? Thx for any suggestions, Vanja ---

@VanjaV Please create multiple taxonomy and train your intelligent classifier and then intelligent form extractor on all 3types of PDFs. The more types/variations of documents , you will train the easier it will be for Document Understanding to extract data correctly. Please have a look at the video below and make sure you are using all components and following all steps.

@[shetanshudhar](https://forum.uipath.com/u/shetanshudhar) Very big thx for advice. I don’t know the logic of UiPath ML Trainer. Let’s say: 1. I define 1st template with Technical Features and corresponding text box (custom area) size 6 wide and 2 tall. 2. Then I define 2nd template with Technical Features and corresponding text box (custom area) size 6 wide and 4 tall. If workflow receives 3rd type of document (that is not defined as template) with Technical Features and corresponding text box (custom area) size 6 wide and 3 tall, how will it respond? Will it be recognized? ---

@VanjaV it will only recognise the templates for which it has been trained. for others it might recognize some content but it would not be a 100%. ---

[shetanshudhar](https://forum.uipath.com/u/shetanshudhar) thx. Sorry, but I don’t get it. Why do you have to train the documents, if it only works with templates? To get all possible combinations in mentioned case I need to prepare around 30-50 different templates. Then, I have same type of document to be applied for more than 100 companies, which multiplies the templates number by indefinite number of combinations. Why can’t I just define the custom area between two paragraph headers (as anchors) either as text or a table? What is the difference between Form Extractor and Intelligent Form Extractor?
