Easy Semantic Search with Upstash Vector
Blog post from Upstash
A tutorial on building a semantic search engine in Python using HuggingFace and Upstash-Vector guides readers through creating a system that matches user questions with relevant posts from a database of 10,000 StackOverflow entries. The process employs the all-MiniLM-L6-v2 model to convert strings into semantic embeddings, which are stored in the Upstash-Vector database using the DiskANN method for efficient retrieval. The tutorial covers initializing the model using the sentence-transformers package, downloading and preparing data, setting up a vector index, and populating the database with encoded entities. It concludes with implementing the search functionality, where queries are encoded and matched to posts based on cosine similarity, demonstrating a quick and accessible approach to semantic search with minimal code and free resources.
