Architecture & Interfaces

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

Problem

LLMs hallucinate without context. Vector databases are complex to manage.

Solution

OpenSearch as hybrid search store (keyword + vector). Optimized retrieval queries for precise LLM answers.

E-Commerce Search Tuning

Problem

Customers don't find products when they misspell technical terms or part numbers.

Solution

Custom N-Gram tokenizers and phonetic analysis that finds 'screwdriver' even with dialect/typos.

Infrastructure, integration and operations

OpenSearch as part of your infrastructure

We do more than provide an application. WZ-IT designs the technical architecture, integrates network and identity, operates the agreed scope and develops integrations when the standard product is not enough.

Architecture and migration

Sizing, target environment, data transfer, cutover and recovery are resolved before production operations.

Network and identity

SSO, secure access, internal systems and existing security components are integrated appropriately.

Monitoring and service level

Updates, backups, technical monitoring and response paths follow a transparent operational scope.

Integration and development

APIs, automation and custom extensions can be delivered beyond basic deployment.

The exact scope depends on the application, edition, infrastructure and criticality. Vendor licences and non-standard components are quoted separately.

Target architecture

Integrate OpenSearch into your infrastructure with clear controls

Data platforms are designed around access patterns, consistency, growth, recovery and the applications that depend on them.

The diagram is a resilient target model. Its implementation depends on edition, data flows, load, availability objectives and existing infrastructure.

Communication with WZ-IT was open, friendly and professional from the very beginning. Mr. Wevelsiep and Mr. Zins responded to every one of our questions patiently, promptly and respectfully, and contributed their own suggestions and good ideas on how to modernize our server infrastructure and adapt it even better to our needs. Throughout, WZ-IT consistently kept our need for data sovereignty and GDPR compliance in mind. Even short-notice adjustments and change requests from our side were implemented quickly and patiently and integrated consistently into the overall concept. From planning to the final handover, every step was documented transparently and comprehensively - so if a provider change should ever become necessary, the documentation would let us onboard a successor into our infrastructure very quickly. We are extremely satisfied with WZ-IT and hope to continue working together for a long time.

WZ-IT provided very competent support in implementing our server and virtualization infrastructure. As part of the project, a Proxmox-based virtualization environment was set up along with a virtual machine for our application systems. Additionally, a structured backup concept was implemented. A particular focus was on security: the setup of a VPN tunnel and the clean implementation of encryption and access concepts were professionally executed. The structured consulting as well as the reliable and swift implementation deserve special mention. We are very satisfied with the services provided and are happy to recommend WZ-IT.
