Understanding how Candidate Search AI finds the right talent

AI Search is the next generation of candidate discovery. Instead of relying only on keywords, it uses artificial intelligence to understand meaning, context, and intent—just like a human recruiter would when reading a resume.

Here’s how it works and why it gives you better, more accurate results.


🔍 It starts by understanding what you mean, not just what you type

Traditional search engines match exact words.
AI Search goes deeper.

When you type something like:

“Senior React developer with fintech experience in London.”

AI interprets:

  • The seniority level

  • The tech stack

  • The industry

  • The location

  • Related skills and synonyms

It transforms your sentence into a structured, intelligent search query.


🧠 AI Search uses Semantic Search, not just keywords

In most ATS systems, search is keyword-based:

  • It looks for exact words

  • Misses variations (“ReactJS” vs “React”)

  • Doesn’t understand context

  • Doesn’t know roles, industries, or skill relationships

AI Search replaces this with Semantic Search — search based on meaning.

This allows the system to understand:

  • Skill variations (React ↔ ReactJS ↔ React Native)

  • Related concepts (“Financial systems” for fintech roles)

  • Equivalent job titles (“Senior Backend Engineer” ≈ “Senior Developer”)

  • Misspellings and language differences

It connects the dots the way a human does.


🧩 Smart Synonym Matching (behind the scenes)

Candidates describe skills differently.

AI Search automatically picks up:

  • Synonyms

  • Abbreviations

  • Common misspellings

  • Localized terminology

  • Industry-specific equivalents

You don’t have to think of every variation—AI does that for you.

For example:

  • “RN” ↔ “Registered Nurse”

  • “AP” ↔ “Accounts Payable”

  • “Forklift Driver” ↔ “Forklift Operator”

  • “CSR” ↔ “Customer Service Representative”


⚡AI blends Semantic Search with keyword precision

AI Search doesn’t throw away keywords—it combines both:

  • Keywords ensure accuracy when you need exact terms

  • Semantic Search broadens the search to include relevant matches

  • Re-ranking models sort results by relevance

This hybrid approach gives you:

  • More complete results

  • Fewer false negatives

  • Better matches in the top positions


📄 It reads the full candidate profile

Instead of scanning only a few fields, AI Search analyzes:

  • The entire resume (profile data)

  • Skills and experience

  • Job history

  • Education

  • Certifications

  • Location preferences

  • Industry background

This is how AI finds relevant candidates even when the resume wording doesn't match your wording.


🎯 It ranks candidates by relevance

AI doesn’t just return a list—it sorts candidates by how well they match your intent.

It looks at:

  • Skill fit

  • Seniority

  • Industry experience

  • Location match

  • Strength of experience

  • Missing skills

  • Synonym and concept alignment

This ranking helps you see the most relevant candidates first.


💬 It explains why each candidate matches

Each candidate gets an AI-generated summary that highlights:

  • Why the candidate is a fit

  • What skills match your search

  • Anything missing

  • Relevant experience pulled from the resume

This saves you significant time when screening.
