AI Research Platform

Academic search is evolving rapidly.While traditional Boolean searches still have their place, AI-powered semantic search is revolutionizing how we discover research. This guide will teach you when to use each approach and how to combine them for comprehensive, efficient literature discovery.

The Evolution of Academic Search

Traditional Boolean Search

How it works:

Matches exact keywords using operators (AND, OR, NOT)

Best for:

  • • Precise terminology searches
  • • Systematic reviews
  • • Specific author/journal searches

Limitations:

  • • Misses synonyms
  • • Requires exact terms
  • • Complex syntax needed

AI Semantic Search

How it works:

Understands meaning and context, not just keywords

Best for:

  • • Conceptual exploration
  • • Interdisciplinary research
  • • Natural language queries

Advantages:

  • • Finds related concepts
  • • Natural language input
  • • Contextual understanding

The Power of Combination

The most effective researchers don't choose one method over the other—they combine both approaches strategically. Use AI for discovery and exploration, then Boolean search for precision and completeness.

When to Use Each Search Method

🔍 Scenario: Exploring a New Research Area

You're starting research in an unfamiliar field and need to understand the landscape.

Start with AI Search

  • • Use natural language descriptions
  • • Let AI suggest related terms
  • • Find key authors and concepts
  • • Discover interdisciplinary connections

Follow with Boolean

  • • Search for specific terms found
  • • Target key authors systematically
  • • Ensure comprehensive coverage
  • • Find seminal works

📋 Scenario: Conducting a Systematic Review

You need comprehensive, replicable search strategies for a systematic review.

Primary: Boolean Search

  • • Documented, replicable queries
  • • Exhaustive synonym lists
  • • Multiple database searches
  • • Transparent methodology

Supplement with AI

  • • Identify missing synonyms
  • • Cross-check concept coverage
  • • Find edge cases
  • • Validate search completeness

🔗 Scenario: Interdisciplinary Research

Your research spans multiple fields with different terminologies.

Primary: AI Search

  • • Bridges terminology gaps
  • • Finds cross-field connections
  • • Understands concept relationships
  • • Discovers unexpected links

Refine with Boolean

  • • Target specific field databases
  • • Use field-specific terms
  • • Ensure depth in each area
  • • Validate with experts

Boolean Search Mastery

Master these Boolean operators and techniques for precise, comprehensive searches:

Essential Boolean Operators

AND

Intersection

Both terms must appear

artificial AND intelligence
OR

Union

Either term can appear

AI OR "machine learning"
NOT

Exclusion

Exclude specific terms

AI NOT robotics

Advanced Techniques

Wildcards & Truncation

educat*

Finds: education, educational, educator

wom?n

Finds: woman, women

Phrase Searching

"machine learning"

Exact phrase match

NEAR/3 (AI, ethics)

Words within 3 positions

Field Searching

Target specific parts of articles for more precise results:

TI:(artificial intelligence)

Search in title

AB:(machine learning)

Search in abstract

AU:(Smith, J.)

Search by author

AI Search Optimization

Get better results from AI-powered search with these proven strategies:

1
Write Descriptive Queries

❌ Too Brief

"AI education"

❌ Too Technical

"CNN RNN LSTM NLP classification accuracy F1-score"

✅ Just Right

"How artificial intelligence tutoring systems improve student learning outcomes in mathematics compared to traditional teaching methods"

2
Use Context and Constraints

Add Context

  • • Population: "in undergraduate students"
  • • Setting: "in online learning environments"
  • • Time: "during the COVID-19 pandemic"
  • • Scope: "systematic reviews and meta-analyses"

Set Constraints

  • • Exclude: "not including K-12 education"
  • • Focus: "specifically peer-reviewed research"
  • • Recent: "published in the last 5 years"
  • • Methodology: "experimental or quasi-experimental studies"

3
Iterate and Refine

1

Start Broad

Begin with general concepts to see what AI finds

2

Analyze Results

Look at what AI considers relevant - learn from the patterns

3

Refine Query

Add specificity based on what you learned

4

Repeat

Keep refining until results match your needs

Database-Specific Search Tips

Each academic database has its own strengths and search syntax. Here's how to optimize for the major platforms:

PubMed/MEDLINE

Strengths:

Medical/health sciences, MeSH terms, clinical studies

Pro Tips:

  • • Use MeSH terms for precision
  • • [tiab] for title/abstract search
  • • Filter by study type

Google Scholar

Strengths:

Broad coverage, citations, interdisciplinary

Pro Tips:

  • • Use quotes for exact phrases
  • • author: for specific authors
  • • Sort by date for recent work

Web of Science

Strengths:

Citation analysis, impact metrics, STEM fields

Pro Tips:

  • • TS= for topic search
  • • Use citation mapping
  • • Analyze research fronts

Scopus

Strengths:

Multidisciplinary, author profiles, analytics

Pro Tips:

  • • TITLE-ABS-KEY for comprehensive
  • • Use subject area limits
  • • Track author impact

The Hybrid Approach: Best of Both Worlds

The most effective search strategy combines AI and traditional methods strategically. Here's your step-by-step workflow:

The 5-Phase Hybrid Search Workflow

1

AI Exploration Phase

Start with INRA.AI to understand the research landscape

✓ Discover key concepts and terminology

✓ Identify major authors and papers

✓ Find interdisciplinary connections

2

Systematic Boolean Search

Use findings to build comprehensive Boolean strategies

✓ Create exhaustive synonym lists

✓ Search multiple databases

✓ Document all search strings

3

AI-Powered Screening

Let AI help prioritize and screen results

✓ Rank papers by relevance

✓ Identify highly cited works

✓ Flag potential duplicates

4

Gap Analysis

Use AI to identify what might be missing

✓ Check for missed concepts

✓ Verify author coverage

✓ Cross-reference citations

5

Final Validation

Combine both approaches for comprehensive coverage

✓ Compare AI vs. Boolean results

✓ Document final methodology

✓ Create replicable process

Result: More Comprehensive Coverage

Researchers using this hybrid approach consistently find more relevant papers than those using either method alone, while significantly reducing search time. The combination ensures both breadth (AI discovery) and depth (Boolean precision).
