Semantic code search - finds code by meaning, not just keywords. Helpful when: - User asks WHERE or HOW something is implemented ("where is X handled", "how does Y work", "where are Z". "how are X", "explain Y", "find where X") - User searches for an explanation on certain behavior - You need to understand code behavior without knowing exact function names - Exploring unfamiliar codebases where you don't know the terminology yet - You need to find the exact file and linenumber without classical grep through the whole filebase - "find the X code" - "show me X" - "X implementation" - "look up X" - "search for X" - Any question about code that isn't a known file path
