Generally, the problem with the type of search VSCode does is:
1. It returns zero results because you made a typo or added a term that doesn’t exist in any document. Codebased uses semantic search so it’s better at this, but if you typed in something random, i.e. “argle bargle” it won’t return results.
2. It returns too many results and they’re not guaranteed to be in order of relevance. This can happen if you type in a commonly used function or class name. Codebased actually ranks code blocks using BM25 and L2 distance before sending them to the reranker for even better results.
