 Sometimes context alone isn’t enough. Sometimes you need precision, too. Dense vectors are fantastic when you need to retrieve results based on the context or meaning behind the data. Sparse vectors are useful when you also need **keyword or specific attribute matching**.

 ## Multitenancy: Data Isolation for Multi-Tenant Architectures

 Sharding efficiently distributes data across nodes, while replication guarantees redundancy and fault tolerance. But what happens when you’ve got multiple clients or user groups, and you need to keep their data isolated within the same infrastructure?
 
 **Multitenancy** allows you to keep data for different tenants (users, clients, or organizations) isolated within a single cluster. Instead of creating separate collections for `Tenant 1` and `Tenant 2`, you store their data in the same collection but tag each vector with a `group_id` to identify which tenant it belongs to.

 As we've seen in this article, a vector database is definitely not **just** a database as we traditionally know it. It opens up a world of possibilities, from advanced similarity search to hybrid search that allows content retrieval with both context and precision. 
 
 But there’s no better way to learn than by doing. Try building a [semantic search engine](https://qdrant.tech/documentation/tutorials/search-beginners/) or experiment deploying a [hybrid search service](https://qdrant.tech/documentation/tutorials/hybrid-search-fastembed/) from zero. You'll realize there's endless ways you can take advantage of vectors.
