allow document search on attachment referenced by url.

[admorelli]

Hello.

First of all thanks for the amazing project.
I'm one of the developers associated to the SireHP project.
But my main language is C# with makes helping the project a struggle :).

Anyway, our project is using only the metadata from a shared library, and i'm trying to make the document content search work.
So i want your opinion, along with the community.

How do i can come about for downloading the resource linked via url and use it as if it was a attachment.

As a example for this record:
https://sirehp.historiadapsicologia.com.br/bibliography/?page=3&page-len=1&id=ZNMAJLSC

i want to download the google drive file and use its content for the document souce.

Is it possible, how can i go about achieving that?
