Description

Enter a topic phrase, and it will automatically break down the structure using the Reverse Onion Method → expand synonym groups → generate four-layer search formulas (CNKI + WoS/Google Scholar), along with an execution checklist and filtering strategies. Suitable for all disciplines; search formulas can be directly copied and used. 🎯 What pain points does it solve? ❌ Entering a full sentence directly in the search box → 0 results ❌ Searching only one keyword → 5000 results, overwhelming ❌ Can't break down the topic → no direction for search terms ✅ Input 'Middle-class educational anxiety and shadow education practices' → outputs 30+ ready-to-paste search formulas + synonym table + layered execution checklist 📐 Core Method: Reverse Onion Method From inside out, from narrow to wide, three layers of progressive expansion – core layer precisely locks in 4 must-read papers, expansion layer finds 48 directly related studies, panoramic layer builds domain volume awareness. 🔧 Output includes: • Three-element topic breakdown (modifier + research unit + research dimension) • 5-8 synonym concepts per element, with Chinese-English pairs, superordinate/subordinate concepts • Layer 1: 8 groups of three-element combined search formulas (title → topic, tight → loose) • Layer 2: 3 types of two-element pairings (annotated core/background usage) • Layer 3: Single-element panoramic search formula • Layer 4: Superordinate concept expansion strategy • 📋 Six-step execution checklist + filtering criteria per layer (highly cited + most recent) 👥 Who is it for? Academic beginners, graduate students, early-career researchers – anyone who needs systematic literature search rather than keyword guessing.
