Qdrant is designed as an efficient vector database, allowing for a quick search of the nearest neighbours. But, you may find yourself in need of applying some extra filtering on top of the semantic search. Up to version 0.10, Qdrant was offering support for keywords only. Since 0.10, there is a possibility to apply full-text constraints as well. There is a new type of filter that you can use to do that, also combined with every other filter type.

Hi there, we encourage authors to share their entire posts here on DEV, rather than mostly pointing to an external link. Doing so helps ensure that readers don’t have to jump around to too many different pages, and it helps focus the conversation right here in the comments section.
If you choose to do so, you also have the option to add a canonical URL directly to your post.
