Summary  
This chapter covers refining AI query prompts by specifying precise filtering criteria to guide web searches toward the resources that address your actual knowledge gap.  

General domain of usage  
Spreadsheet functions tutorials


Ask Claude "find me resources for learning Excel" and web_search does exactly what you'd expect: returns a wall of beginner tutorials covering stuff you already know, none of them touching the one thing you're actually stuck on.



The fix isn't a different tool — it's telling Claude what to filter for before it searches:



Your specific gap — "multi-condition XLOOKUP"

Your actual level, so beginner filler gets skipped

One clear pick, not a list to sort through yourself

Same search engine either way. The difference is whether Claude knows enough about your actual gap to filter for it.
