 Effective use:
 - Provide a detailed query for accurate relevance ranking
-- Include extensive but uncommon keywords to ensure comprehensive results
-- Order keywords by importance (most important first) - less important keywords may be dropped if there are too many results
+- Prefer MANY SPECIFIC terms over FEW GENERAL ones (high precision beats high recall)
+- Order search terms by importance (most important first)
+- Supports regex search terms for flexible matching
 
 IMPORTANT: Do NOT use this tool if you have precise information like log lines, error messages, filenames, symbols, or package names. Use direct approaches (grep, cat, go doc, etc.) instead.
