2Develop Search Strategy
| Concept 1: Population | Concept 2: Intervention | Concept 3: Outcome |
|---|---|---|
| diabetes OR diabetic* OR "diabetes mellitus" OR T2DM OR "type 2 diabetes" | exercise OR "physical activity" OR workout OR training OR fitness | "blood glucose" OR glycemic OR HbA1c OR "glucose control" |
Combine columns with AND, terms within columns with OR

π― Search Optimization Techniques
π‘ Keyword Development Strategy
- Identify Core Concepts: Break research question into 2-4 main concepts
- Generate Synonyms: Use thesauri, subject headings, and related articles
- Consider Variations:
- Spelling variants (pediatric/paediatric)
- Abbreviations (AI, artificial intelligence)
- Truncation (child* = child, children, childhood)
- Regional terms (elevator/lift)
- Test and Refine: Run preliminary searches and adjust
β Sensitivity Approach
Goal: Find everything relevant
- Broad search terms
- Multiple synonyms
- Minimal limits
- Multiple databases
Use for: Systematic reviews
π― Precision Approach
Goal: Find most relevant
- Specific terms
- Subject headings
- Applied filters
- Recent publications
Use for: Quick searches
π Documentation Best Practices
ποΈ Search Documentation Checklist
- Date and time of each search
- Database name and interface/platform
- Complete search strategy (copy/paste exact syntax)
- Number of results retrieved
- Any limits or filters applied
- Export format and number of records saved
- Notes on modifications or issues encountered
Database: PubMed (via NCBI)
Date: January 15, 2025
Search String: ((diabetes[MeSH] OR diabetic*[tiab]) AND (exercise[MeSH] OR "physical activity"[tiab]) AND ("blood glucose"[MeSH] OR HbA1c[tiab]))
Filters: Publication date 2020-2025, English, Humans
Results: 347 records
Exported: RIS format to Zotero
π Boolean Logic & Advanced Search Techniques
Boolean operators form the foundation of systematic database searching, enabling precise query construction and efficient information retrieval across all platforms.
βοΈ Core Boolean Operators
AND - Narrows Results
Returns records containing BOTH terms
Use when: Combining different concepts
OR - Broadens Results
Returns records containing ANY term
Use when: Including synonyms/variants
NOT - Excludes Results
Excludes records with specified term
Caution: May eliminate relevant records
1Nesting with Parentheses
Control the order of operations for complex searches:
Unclear - processes as (diabetes AND exercise) OR diet
Nested: diabetes AND (exercise OR diet)
Clear - diabetes must appear with either exercise or diet
Complex: (diabetes OR diabetic*) AND (exercise OR "physical activity" OR fitness) AND (glycemic OR glucose OR HbA1c)
