What is an extractor?
An extractor is a core feature in AlgoDocs that consists of a set of rules (extracting rules) that are used to extract data from documents. So, your entire data extraction lifecycle can start by firstly creating an extractor.
In general, you should create an extractor for every document that has a different layout. So, in other words you should create different extracting rules for documents with different layouts. However, in cases that your documents have similar layouts, then there are ways of creating only one extractor with more flexible extracting rules. You can find more information on creating different extractors with various extracting rules in other articles under Extracting Rules category.
