I am writing an article about the extraction of an entire text from a document. I am not sure if I should use "a", "the", or nothing in "extract text" phrases.
- "How to extract text from non-searchable PDF."
- "You need to perform OCR to extract text from non-searchable PDF documents."
- "For searchable PDFs, you can extract text without recognition."
Here I mean the extraction of all text in the document. I.e. we cannot extract 2 different texts from the document. And I do not mean that we need to extract some specific text. We just need all document's text.
Am I right that "text" is uncountable in samples 1-3 and does not require an article?
- "You can extract a text manually. Open a document, then select and copy some text."
Am I right that "text" is countable here and requires "a" article?
