Search & Relevance Engineering
We build search that understands what your users mean — not just what they type. Semantic retrieval, vector embeddings and learning-to-rank models that turn a sea of documents, products and tickets into fast, precise, trustworthy answers. Production systems, not search-box demos.
The retrieval engineering behind IntelloWork (enterprise search & RAG chatbot) and the DPDP-aware data handling proven in ProtectComply.
Search That Understands Intent, Not Just Keywords
Keyword search fails the moment a user phrases things differently than your content does. We engineer retrieval that captures meaning — so “can’t log in on mobile” finds the authentication article that never uses those exact words.
Intent, Context and Behavior in the Ranking
We combine lexical matching, semantic embeddings and behavioral signals — clicks, dwell time, conversions — into a ranking model tuned to your users. The result is fewer “no results” dead ends and more first-click answers.
Every ranking decision is measurable. We build an evaluation set from real queries so relevance is a number we improve against, not a matter of opinion.
Relevance Signals That Move Real Metrics
Better relevance is not an academic goal — it lifts engagement, cuts bounce and shortens the path to conversion. We weight freshness, personalization and popularity alongside semantic match so the right result surfaces for each user.
As your catalog and traffic grow, the architecture grows with it — the same scalable retrieval discipline we applied building IntelloWork’s enterprise search.
Vector Search & RAG for High-Performance Platforms
When users face millions of documents or products, retrieval quality is the product. We build indexing and ranking pipelines that stay fast and accurate as your data scales.
Fast Indexing, Real-Time Ranking, Tuned Embeddings
We choose the right engine for the job — Elasticsearch/OpenSearch, pgvector, or a dedicated vector database — and tune chunking, embeddings and re-ranking for precision at your latency budget.
Hybrid retrieval (lexical plus vector) gives you the recall of keyword search with the understanding of semantic search, with sub-second response even at scale.
Grounded Answers with Citations, Not Hallucinations
Retrieval-augmented generation (RAG) turns your search index into an assistant that answers in natural language — strictly from your trusted sources, with citations back to the document.
This is the exact architecture behind IntelloWork: relevance-tuned retrieval feeding an LLM, with access controls so users only ever see what they’re permitted to.
Semantic Search and Relevance Optimization
Semantic understanding sits at the core of everything we build — interpreting intent, relationships and context so results feel obvious to the user.
Intent Understanding
Interpret what users actually want, not just the exact words they type — synonyms, misspellings and natural phrasing included.
Hybrid Retrieval
Blend lexical and vector search for high recall and high precision, with re-ranking to put the best answer first.
Behavior Learning
Learn from clicks, conversions and feedback to continuously improve ranking quality with real traffic.
Evaluation & Guardrails
A golden query set and offline metrics (NDCG, recall) so every change is measured, not guessed.
Enterprise Search Engineering for Scalable Growth
Enterprises deal with complex data across many sources and user roles. We build secure, scalable search that handles large datasets and permission-aware access without slowing down.
Enterprise Search Architecture
Robust search requires secure ingestion, intelligent indexing, tuned ranking and analytics-driven optimization — each layer instrumented and measurable.
Data Sources
Connect documents, products, repositories, databases, APIs and enterprise systems with permission metadata intact.
Indexing Layer
Build fast, scalable indexes with structured fields, metadata and vector embeddings tuned to your domain.
Ranking Layer
Apply relevance scoring, semantic matching, personalization and behavioral signals — then re-rank for precision.
Discovery Experience
Deliver reliable search, filters, recommendations, RAG answers and analytics that keep improving.
How We Build Your Search System
A pragmatic path from a query log to relevance your users trust in production.
Discover & Baseline
We analyze your query logs, build a golden evaluation set and measure where current search fails users today.
Prototype & Evaluate
A working retrieval prototype in a few weeks — hybrid search and re-ranking, scored against real queries, not a cherry-picked demo.
Harden & Secure
Permission-aware retrieval, PII handling, latency and cost controls, and monitoring so it’s safe to run at scale.
Deploy & Improve
Ship to your stack with relevance dashboards and a feedback loop that keeps ranking improving on live traffic.
Search & Relevance Engineering FAQs
What’s the difference between keyword search and semantic search?
Keyword search matches the literal words in a query against your content, so it misses synonyms and natural phrasing. Semantic search uses vector embeddings to match on meaning, so a query like “can’t sign in” still finds your “authentication error” article. In practice we usually run both as hybrid retrieval for the best recall and precision.
Do we have to replace our existing search engine?
Not necessarily. We often improve relevance on top of your current Elasticsearch, OpenSearch, Algolia or database search by adding vector retrieval, re-ranking and better tuning. We recommend a full replacement only when the existing stack genuinely can’t meet your goals.
How do you measure whether search actually got better?
We build a golden set of real queries with expected results and track offline metrics like NDCG and recall, plus live signals such as click-through, zero-result rate and conversions. Every change is measured against that baseline, so “better relevance” is a number, not an opinion.
Can search respect our permissions and keep data private?
Yes. We build permission-aware retrieval so users only see documents they’re allowed to, mask or exclude PII where needed, and can run entirely within your cloud or VPC — the same DPDP-aware data discipline we applied on ProtectComply.
Can you add an AI assistant on top of our search?
Yes — that’s RAG. Once retrieval is solid, we layer an LLM that answers in natural language strictly from your indexed sources, with citations. It’s the same architecture behind IntelloWork, our enterprise search and RAG chatbot.
