Support searching multiple collections based on a name pattern (glob-like)

[igoristic]

Elasticsearch has a feature where we can search multiple indices (like collections in Qdrant) with a single query. Example:

If we have the following collections:

20230101_cats
20230201_cats
20230101_dogs
20230201_dogs

And we do a search on pattern like this:

202301*,-*_dogs

it will only search in one collection:

20230101_cats

Since the pattern states to include everything that matches 202301*, and exclude (notice the -) everything that matches *_dogs

---

Another example:

*_dogs

Would only search in the following collections:

20230101_dogs
20230201_dogs

---

I wrote something similar for Kibana a while back that might give you a good idea about the logic: https://github.com/igoristic/kibana/blob/1e5e9876666ee14cd869e4f80706e348218066d8/x-pack/plugins/monitoring/common/es_glob_patterns.ts

Thank you Qdrant team, for such an awesome product and constant releases 🙇 ❤️ ❤️

Any updates on this? We could make an issue as "feature request" to talk about this. It would be a great addition!

In Qdrant, Multitenancy is done in a single collection through payloads.

This, and reasoning behind it, is described here: https://qdrant.tech/documentation/guides/multiple-partitions/
