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 🪐

https://docs.neynar.com/reference/search-casts

as promised - algorithmic ranking is now available on cast search API

all put together 👇🏽

1. cast search now looks at similar casts that don't necessary have the keyword w/ semantic search

2. ranks results algorithmically instead of just chronologically (good example is to search for a token and see the quality difference between chronological and algo)

3. latency is much faster with p95 <100 ms

feedback and feature requests are welcome, h/t @vrose.eth for the continued work here
