From Keyword Matching to True AI Search: How Wiggli Intelligence Is Redefining Recruitment

As part of our ongoing mission to make recruitment smarter, faster, and more human, Wiggli continues to innovate through the power of AI and data intelligence.

In this article, we take a closer look at Wiggli Intelligence — our semantic and vector-based search technology and how it moves beyond traditional keyword matching to deliver a truly intent-driven recruitment experience for both recruiters and candidates.

The Problem: When “AI Search” Isn’t Really Intelligent

Over the past few years, many recruitment platforms have introduced so-called “AI-powered search.”

But in reality, most of these systems simply translate a user’s prompt into a list of keywords, running a slightly improved version of traditional database lookups.

Let’s consider a simple example.

A recruiter searches for:

"Senior backend developer experienced with distributed systems and cloud scalability."

Most systems convert this into terms like backend, developer, cloud, senior, and distributed systems — and search for exact or partial text matches.

The issue? These systems don’t understand context or intent.

A candidate who writes “software engineer building large-scale microservices on AWS” might never appear, even though they’re a perfect fit.

That’s the limitation of keyword-based or "pseudo-AI" search: it translates queries, but it doesn’t comprehend meaning.

The Shift: Semantic and Vector Intelligence

At Wiggli, we wanted to go further.

Our team designed Wiggli Intelligence, a search engine that uses semantic embeddings and vector similarity models to understand meaning, not just words.

When a recruiter types a natural-language prompt, our system doesn’t extract keywords.

It encodes the intent into a multidimensional vector representation, capturing concepts, relationships, and context.

Example:

• Recruiter searches: "backend developer with Python and API experience."

Wiggli retrieves profiles such as "software engineer building Flask-based microservices" or "backend developer working with RESTful APIs."

Different words, same meaning — that’s the foundation of semantic understanding.

Inside Wiggli Intelligence

Behind the scenes, Wiggli Intelligence processes and structures millions of candidate profiles, representing terabytes of data on experience, skills, industries, and education ...

To achieve this level of scale and intelligence, our architecture combines:

• Generative AI for data enrichment, summarization, and multilingual normalization.

• Vector databases and embeddings for semantic retrieval and context-based ranking.

• Massive data pipelines continuously ingesting and updating millions of records in near real time.

• Cloud-native distributed infrastructure built on AWS ECS, MongoDB Atlas, and Elasticsearch ... optimized to handle billions of vector operations efficiently.

• AI ranking models capable of understanding seniority, role relevance, and contextual fit.

Every search runs across a distributed, high-performance system capable of returning semantic results within milliseconds, even under heavy load.

Real Impact for Recruiters

This is not just a technical improvement, it’s a tangible operational advantage.

Before Wiggli Intelligence:

• Recruiters needed to test multiple keyword combinations.

• Many relevant candidates were missed due to differences in wording.

• Search was manual, reactive, and time-consuming.
  

With Wiggli Intelligence:

• Recruiters can express their needs naturally; the system understands their intent.

• AI models infer skills, experience level, and potential — not just word matches.

• Search becomes proactive: faster, richer, and more relevant.

The result: less time filtering, more time engaging with the right talent.

Beyond Search — Toward Understanding

The shift from keyword-based search to intent-based discovery represents a fundamental change in recruitment technology.

It’s no longer about querying databases — it’s about building systems that understand human needs.

At Wiggli, our vision is to create technology that connects human intention with human potential.

That’s what true AI-driven recruitment looks like.

Conclusion

AI in recruitment is often used as a buzzword, but at Wiggli, it’s an engineering reality.

By combining Generative AI, semantic and vector search, and massive-scale data intelligence, we’re building a platform that helps companies discover talent not by keywords, but by meaning.

We believe this is how the future of recruitment will be shaped — through technology that truly understands people.
