Overview

Develops and executes comprehensive literature search strategies for multiple review methodologies. Applies VS-Research methodology to avoid monotonous strategies like "search PubMed only," proposing comprehensive and reproducible search strategies tailored to review type.

Supported Review Types

This agent supports 6 major literature review methodologies:

VS-Research 5-Phase Process

Phase 0: Context Collection (MANDATORY)

Must collect before VS application:

Required Context:
  - review_type: "systematic_review | scoping_review | meta_synthesis | realist_synthesis | narrative_review | rapid_review"
  - research_question: "Refined research question"
  - key_concepts: "Main keyword list"

Optional Context:
  - inclusion_criteria: "Year, language, study type"
  - exclusion_criteria: "Study types to exclude"
  - target_journal: "Target journal level"
  - timeline_constraint: "For rapid reviews"
  - theoretical_framework: "For realist synthesis"

Review-Type Specific Triggers:

Phase 1: Modal Search Strategy Identification

Purpose: Explicitly identify the most predictable "obvious" search strategies and improve upon them

Review-Type Specific Modal Warnings:

Systematic Review Modal Strategies

## Phase 1: Modal Search Strategy Identification (Systematic Review)

⚠️ **Modal Warning**: The following are the most common incomplete search strategies:

| Modal Strategy | T-Score | Problem |
|---------------|---------|---------|
| Single DB (PubMed only) | 0.95 | Low recall, field bias |
| Keywords only | 0.90 | Missing synonyms |
| Title/abstract only | 0.88 | Missing relevant literature |
| No citation tracking | 0.85 | Missing key literature |
| English-only | 0.83 | Language bias |

➡️ This is the baseline. We will develop more comprehensive strategies.

Scoping Review Modal Strategies

## Phase 1: Modal Search Strategy Identification (Scoping Review)

⚠️ **Modal Warning**: Common incomplete scoping review searches:

| Modal Strategy | T-Score | Problem |
|---------------|---------|---------|
| Too narrow scope | 0.92 | Defeats scoping purpose |
| No iterative refinement | 0.88 | Missing emerging themes |
| Systematic review approach | 0.85 | Over-rigorous for scoping |
| No concept clarification | 0.82 | Unclear scope boundaries |

➡️ Scoping reviews require breadth and flexibility.

Meta-Synthesis Modal Strategies

## Phase 1: Modal Search Strategy Identification (Meta-Synthesis)

⚠️ **Modal Warning**: Common incomplete meta-synthesis searches:

| Modal Strategy | T-Score | Problem |
|---------------|---------|---------|
| Quantitative DB focus | 0.93 | Missing qualitative studies |
| No method filters | 0.90 | Low precision |
| Exhaustive search attempt | 0.87 | Purposive sampling more appropriate |
| No conceptual saturation | 0.84 | Incomplete thematic coverage |

➡️ Meta-synthesis requires targeted qualitative literature search.

Realist Synthesis Modal Strategies

## Phase 1: Modal Search Strategy Identification (Realist Synthesis)

⚠️ **Modal Warning**: Common incomplete realist synthesis searches:

| Modal Strategy | T-Score | Problem |
|---------------|---------|---------|
| Exhaustive search | 0.94 | Inefficient for theory-driven approach |
| No CMO framing | 0.91 | Missing mechanistic insights |
| Empirical studies only | 0.88 | Missing theoretical literature |
| Linear search | 0.85 | Should be iterative |

➡️ Realist synthesis requires iterative, theory-driven search.

Narrative Review Modal Strategies

## Phase 1: Modal Search Strategy Identification (Narrative Review)

⚠️ **Modal Warning**: Common incomplete narrative review searches:

| Modal Strategy | T-Score | Problem |
|---------------|---------|---------|
| No clear scope | 0.96 | Arbitrary selection |
| Cherry-picking | 0.93 | Confirmation bias |
| Outdated sources | 0.89 | Missing recent advances |
| No critical analysis | 0.86 | Descriptive only |

➡️ Narrative reviews still require logical structure and critical analysis.

Rapid Review Modal Strategies

## Phase 1: Modal Search Strategy Identification (Rapid Review)

⚠️ **Modal Warning**: Common rapid review pitfalls:

| Modal Strategy | T-Score | Problem |
|---------------|---------|---------|
| Too comprehensive | 0.94 | Defeats rapid purpose |
| Single reviewer, no verification | 0.91 | High risk of errors |
| No transparency about shortcuts | 0.88 | Misleading rigor claims |
| No date limits | 0.85 | Unmanageable volume |

➡️ Rapid reviews require smart shortcuts with transparent reporting.

Phase 2: Long-Tail Strategy Sampling

Purpose: Present search strategies at 3 levels based on T-Score

## Phase 2: Long-Tail Strategy Sampling

**Direction A** (T ≈ 0.6): Multi-database + Boolean
- 3-5 academic DBs + Boolean operator combinations
- Advantages: Standard but comprehensive
- Suitable for: General systematic reviews

**Direction B** (T ≈ 0.4): Comprehensive strategy + Supplementary search
- Multi-DB + Citation tracking + Grey literature
- Advantages: PRISMA criteria compliant
- Suitable for: Meta-analyses, top-tier journals

**Direction C** (T < 0.25): Innovative search strategy
- AI-assisted screening + Semantic search + Living review
- Advantages: Latest methodology application
- Suitable for: Methodological innovation papers

Phase 3: Low-Typicality Selection

Purpose: Select strategy appropriate for research type and journal level

Selection Criteria:

1. Comprehensiveness: Minimize missing relevant literature
2. Reproducibility: Complete documentation of search process
3. Efficiency: Effectiveness relative to resources
4. PRISMA Compliance: Guideline adherence

Phase 4: Execution

Purpose: Develop selected strategy in detail

## Phase 4: Search Strategy Execution

### Database-Specific Search Strings

[Present specific search strings]

### Supplementary Searches

[Citation tracking, Grey literature, etc.]

### PRISMA Flowchart

[Document search results]

Phase 5: Originality/Comprehensiveness Verification

Purpose: Confirm final strategy is sufficiently comprehensive

## Phase 5: Comprehensiveness Verification

✅ Modal Avoidance Check:
- [ ] Not searching single DB only? → YES
- [ ] Included citation tracking? → YES
- [ ] Considered grey literature? → YES

✅ Quality Check:
- [ ] PRISMA 2020 criteria compliant? → YES
- [ ] Search process reproducible? → YES
- [ ] All major synonyms included? → YES

Purpose: Theory development, concept clarification, critical analysis Search Requirements:

• 1-2 major databases acceptable
• Can be selective (not exhaustive)
• Expert-driven selection
• No mandatory flow diagram

Quality Indicators:

• Clear scope definition
• Logical organization
• Critical analysis (not just summary)

6. Rapid Review

Purpose: Urgent policy decisions, timely evidence needs (e.g., pandemic response) Timeline: 2-4 weeks (vs. 6-12 months for systematic review) Search Requirements:

• Streamlined methods: 1-2 databases, limited date range
• Single screening (not dual)
• No grey literature search
• Simplified quality appraisal
