Search Infra
Design and operate full-text and vector search infrastructure — inverted-index engines (Elasticsearch/OpenSearch, Meilisearch, Typesense), analyzers and tokenization, relevance tuning (BM25, boosting, synonyms), faceting, and semantic/vector search (embeddings, ANN indexes, hybrid retrieval). Use when adding a search box, choosing a search engine, designing an index mapping and analyzer chain, tuning relevance, building autocomplete, deciding keyword vs vector vs hybrid retrieval, or keeping a search index in sync with the source database. Boundary vs db-design — db-design owns the durable transactional source of truth (normalized PostgreSQL schema, known-key indexes, migrations, ACID); this skill owns the derived denormalized search index built FROM that source for ranked free-text/semantic retrieval, where the engine is eventually-consistent, rebuildable, and never the system of record. Defers cache concerns to redis and RAG prompt assembly to llm-patterns.

From the source SKILL.md
A practical guide to building search that returns the relevant result, not just a matching row. Covers classic full-text (inverted index, BM25) and modern semantic (embeddings, vector ANN) retrieval, and the index-sync discipline that keeps either honest. Stack-agnostic; recipes target Elasticsearch/OpenSearch, Meilisearch, Typesense, and pgvector/Qdrant as the reference engines.
What this skill does
Search Infra is a community-contributed Claude Code skill in the databases sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/search-infra/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when adding a search box, choosing a search engine, designing an index mapping and analyzer chain, tuning relevance, building autocomplete, deciding keyword vs vector vs hybrid retrieval, or keeping a search index in sync with the source database. Boundary vs db-design — db-design owns the durable transactional source of truth (normalized PostgreSQL schema, known-key indexes, migrations, ACID); this skill owns the derived denormalized search index built FROM that source for ranked free-text/semantic retrieval, where the engine is eventually-consistent, rebuildable, and never the system of record.
Who uses this skill
The Search Infra Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 176,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

Is this skill free to install?
Yes. ClaudSkills is an open registry — every skill keeps its source repository's license, and manual install via copy is free. ClaudSkills Pro ($9/mo, $79/yr, or $149 one-time) adds one-click install via the desktop app and a multi-signal Quality Score.
When should I use the Search Infra skill?
Use Search Infra when your Claude Code task falls under the Engineering category — specifically in the databases area. Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use Search Infra" or describe the task and let Claude pick). Browse related skills at
/category/engineering/.
What is a Claude Code skill and how does the Search Infra skill fit in?
A Claude Code skill is a
SKILL.md file that lives under
~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Search Infra is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Engineering category. Learn more at
/learn/what-is-a-claude-skill/.
