How to set up a search on the site by text in pdf files?

Question

Bitrix24

The site has a search by parameters: everywhere, knowledge base and documentation.
On the documentation page there is a list with pdf files (when you click on the file, it is downloaded).
The search works only on the main page with documents, but does not search inside the files.

How to implement matched search results inside pdf files?

Answer 1

Recognize PDF into text, after that it will have to search, as in ordinary text files
PDF is the same picture ...

Answer 2

For starters: you need a boxed version of Bitrix24, it will not search in the cloud.
As soon as you put the box, the next thing you need is a console (on the server) utility that will take the path to the file as input, and print it to stdout as output.
Then, in the intranet settings, you need to register this program as a search provider.
And then - in the settings of the disk module, allow indexing of the contents of the file
