SmartSearch Explained: How Semantic Search Finds Better Cases
Discover how LexGyan's SmartSearch uses AI to understand legal concepts, not just keywords, helping you find relevant cases faster.
SmartSearch Explained: How Semantic Search Finds Better Cases
Every lawyer has experienced this frustration: you know the case exists, you remember the principle, but no matter what keywords you try, the search results miss the mark. You end up scrolling through hundreds of irrelevant judgments or giving up entirely.
SmartSearch changes how you find cases. Instead of matching keywords, it understands what you mean.
The Problem with Keyword Search
Traditional legal databases work by matching exact words. Search for “wrongful termination” and you get cases containing those exact words. But what about cases discussing:
- “Illegal dismissal”
- “Arbitrary removal from service”
- “Termination without following procedure”
- “Violation of natural justice in service matters”
All of these discuss the same legal concept, but keyword search misses them if your exact phrase does not appear.
A Real Example
Suppose you are researching this issue:
“Can a landlord evict a tenant for subletting without written permission?”
With keyword search, you might try:
- “subletting without permission eviction”
- “unauthorized sublease landlord”
- “tenant subletting consent”
You will get results where these exact words appear. But you will miss cases discussing:
- “Parting with possession to third party”
- “Transfer of tenancy rights without consent”
- “Breach of covenant against sublease”
With SmartSearch, you simply describe your problem:
“tenant sublet commercial property without landlord’s written consent”
SmartSearch understands you are looking for cases about unauthorized subletting and finds relevant judgments regardless of the specific terminology used.
What is Semantic Search?
Semantic search is powered by AI that understands meaning, not just words.
Here is how it works:
1. Understanding Your Query
When you type a search query, SmartSearch converts it into a mathematical representation (called an “embedding”) that captures its legal meaning. Similar concepts have similar representations.
2. Matching Against the Database
Every judgment in LexGyan has already been processed the same way. The legal issues, holdings, and reasoning have all been converted into these mathematical representations.
3. Finding Conceptual Matches
Instead of looking for word matches, SmartSearch finds cases whose legal concepts are closest to your query, even if different words are used.
How SmartSearch Understands Legal Concepts
SmartSearch is not just generic AI. It has been fine-tuned to understand:
Legal terminology variations
- “Fundamental rights” = “Part III rights” = “constitutional guarantees”
- “Natural justice” = “audi alteram partem” = “principles of fair hearing”
Hierarchical concepts
- Searching for “Article 21” also surfaces cases about “right to life”, “personal liberty”, and “due process”
Contextual meaning
- “Discharge” means something different in contract law versus criminal procedure versus employment law
- SmartSearch understands context from surrounding words
Indian legal specifics
- Understands references to Indian Evidence Act, CPC, CrPC
- Recognizes Supreme Court and High Court naming conventions
- Familiar with Indian legal terminology and Latin maxims
Keyword vs Semantic: Side-by-Side Comparison
| Query | Keyword Results | SmartSearch Results |
|---|---|---|
| ”anticipatory bail economic offences” | Cases with these exact words | Also finds cases discussing “pre-arrest bail”, “Section 438 applications”, “white collar crimes" |
| "specific performance part performance” | Exact phrase matches | Includes cases on “part execution of contract”, “acts in furtherance of agreement”, Section 53A Transfer of Property Act |
| ”delay condonation appeal” | Word matches only | Finds “sufficient cause”, “limitation extension”, Section 5 applications with different terminology |
Tips for Writing Effective Semantic Queries
SmartSearch works best when you describe your legal problem naturally. Here are tips to get better results:
Do: Describe the Situation
Instead of:
“Section 138 NI Act cheque bounce”
Try:
“dishonour of cheque issued for discharge of legally enforceable debt”
Do: Include Relevant Context
Instead of:
“specific performance”
Try:
“specific performance of agreement to sell immovable property where buyer paid substantial consideration”
Do: State the Legal Question
Instead of:
“bail murder”
Try:
“grant of bail in murder case where investigation is complete and trial is delayed”
Avoid: Boolean Operators
SmartSearch does not need AND, OR, NOT operators. Just describe what you want:
| Instead of | Use |
|---|---|
| ”contract AND breach AND damages" | "claim for damages arising from breach of contract" |
| "appeal NOT criminal" | "civil appeal against decree” |
Avoid: Over-specific Citation Hunting
SmartSearch excels at finding conceptually similar cases. If you need a specific citation, use the citation search feature instead.
Combining Filters with Semantic Search
SmartSearch becomes even more powerful when combined with filters:
Narrow by Date
Researching recent developments? Add a date filter:
Query: “interpretation of arbitration clause in commercial contracts” Filter: Cases from 2020-2024
Filter by Bench Size
Looking for authoritative precedents? Filter by bench composition:
Query: “conflict between fundamental rights and directive principles” Filter: Constitution Bench (5+ judges)
Combine with Court Selection
Focus your research by court:
Query: “compensation for land acquisition delay” Filter: Supreme Court only
When to Use Keyword vs Semantic Search
| Use Keyword Search When | Use SmartSearch When |
|---|---|
| You know the exact citation | You are exploring a legal issue |
| Searching for specific party names | Looking for similar fact patterns |
| Finding cases mentioning a statute section | Researching how courts have treated a concept |
| You need exact phrase matches | You want conceptually related cases |
