I have a Firebase collection, and my documents ID are like this :

  • User1-User2
  • User1-User3
  • User2-User4
  • User4-User1

In my Flutter app, I want to get only the documents where the document ID contains "User1".

Is it possible to do it?

While it is possible to search for documents where the ID starts with a certain value, it is not possible to search for document IDs that contain a certain value.

If you need this functionality, the typical solution is to create an additional collection where you map the user ID to the relevant document IDs.

I finally decided to use Algolia, which is an external service allowing to do what I wanted to do. It's really easy to use and really practical ^^ I posted samples of my data into Algolia, and the research worked perfectly ^^

Thank you for your help! :)
