I am considering FoundationDB for a SaaS project. Here are some questions I have:

1. What is the recommended way to filter on multiple indexes?

2. What is the recommended way to filter on one or more indexes and sort on another or more index(es)

3. If I use FoundationDB as my main datastore, how should I implement full text search?

4. From what I understand, FoundationDB stores keys sorted globally. How does it handle hot spots where a range of keys that is very frequently accessed is on one machine that gets overloaded?

Edit 5. How do you do backups?
