OpenSearch Development & Integration
Search is more than `SELECT *`. We optimize OpenSearch for relevance, performance, and AI-powered vector search.
Search Pipelines
Manipulation of queries before execution. We develop request processors that enrich synonyms, correct typos, or analyze user intent.
Ingest Pipelines
ETL directly in the cluster. We write ingest processors that enrich documents upon indexing (GeoIP, NLP sentiment, PII masking).
Vector Search (k-NN)
Implementation of semantic search via k-NN plugin. We connect OpenSearch with embedding models for RAG applications.
Concrete Use Cases
How we implement OpenSearch development in practice.
RAG Knowledge Base
LLMs hallucinate without context. Vector databases are complex to manage.
OpenSearch as hybrid search store (keyword + vector). Optimized retrieval queries for precise LLM answers.
E-Commerce Search Tuning
Customers don't find products when they misspell technical terms or part numbers.
Custom N-Gram tokenizers and phonetic analysis that finds 'screwdriver' even with dialect/typos.
