Introducing semantic search of casts! 🪐

In the `cast/search` route, you can now specify a `mode`, which can be `literal` (searches text for the same words), `semantic` (uses vectors to find casts with similar meaning), or `hybrid` (a combination of literal and semantic).

Try it out and let us know if you have questions!

Big upgrade on the cast search API today - semantic search

We're storing millions of vectors, each vector made within seconds of when a cast hits the network. When a semantic or hybrid search is performed, we get the vector for the search query, find the casts with vectors that are closest in vector space and insert in the API response. 

Up next:
- algorithmic ranking of search results (right now its desc chron only) so the best results show at the top
- any necessary latency improvements

Feedback is useful as always 🪐

Will vectors also be available through your indexing service?

Great updates!
