## The Limitations of Basic Vector Search

In standard RAG applications, a user’s query is converted into a vector and compared against a database document vectors. However, human queries can be messy, brief, or poorly phrased. For example, a user asking “Why is my screen completely black?” is probably looking for troubleshooting steps, but basic vector search might just r
