> Claude/Codex skill by [@elastic](https://omgskills.com/library/elastic/index.md) · 4 stars · Updated 2026-10-23

Design and review Elasticsearch index mappings for stated access patterns: correct field types, text+keyword multi-fields, doc\_values tuning, mapping-explosion avoidance, and explicit shard settings. Use when creating a new index, reviewing a mapping for storage or query performance, fixing wrong field types, or when the user asks which type to use for search, filter, sort, or aggregation on a field.

## Install

```sh
git clone https://github.com/elastic/claude-plugin /tmp/claude-plugin && ln -s /tmp/claude-plugin/skills/elasticsearch/elasticsearch-index-design ~/.claude/skills/elasticsearch-index-design
```

## From README

Elasticsearch Index Design Design explicit index mappings from access patterns, review existing mappings for type and storage mistakes, and apply corrections through a new index plus reindex when field types must change. Environment Configuration This skill executes Elasticsearch operations through the elastic CLI. If the elastic CLI is not installed, tell the user what it is needed for. Do not guess credentials, call the HTTP API directly, or attempt other workarounds. This skill references operations in HTTP-shorthand form (e.g., GET /, GET /cat/indices, GET /{index}/mapping, GET /{index}/settings/index.mode, POST /query). The Operations table at the end of this document maps each shorthand to the equivalent elastic CLI command — always use the CLI rather than calling the HTTP API directly. Process Gather access patterns per field. Before choosing types, list how each field is used. For every field capture: Search — full-text match, phrase, relevance scoring?
