Harnessing Semantic Search in SQL Databases with Langchain and PGVector Introduction: Revolutionizing Data Retrieval with Semantic Search In the ever-evolving world of data management, the ability to search and retrieve information based on semantic meaning rather than just keywords or exact matches is a game-changer. This is where the combination of Langchain and PGVector comes into play, offering a powerful way to perform semantic searches within SQL databases. In this blog, we’ll explore how to incorporate semantic similarity in tabular databases, a technique that can significantly enhance the way we interact with data.
