MongoDB Atlas Search (Lucene Full-Text)
- Comprehensive reference for MongoDB Atlas Search - the Lucene-based full-text search engine embedded in Atlas. Covers the full lifecycle from index design through query construction, relevance tuning, and production deployment. Explicitly excludes Vector Search ($vectorSearch); see [[mongodb-search-ai]] for hybrid and semantic patterns. [source]
When to Use This Skill
- Building full-text search features: search bars, typeahead, faceted filtering [source]
- Relevance-ranked results with BM25 scoring [source]
- Complex text queries: phrase, fuzzy, wildcard, regex, proximity [source]
- Faceted navigation (e-commerce filters, category counts) [source]
- Autocomplete / search-as-you-type [source]
- Multi-language content with language-specific analyzers [source]
- Rich scoring control: boost, decay, function score [source]
- Cluster tier requirement: Atlas Search requires M10 or higher. Not available on M0 (free), M2, or M5 shared-tier clusters. [source]
- Do NOT use Atlas Search when: [source]
- You need immediate consistency - indexes are eventually consistent via change streams [source]
- Exact-match on a handful of fields - standard B-tree compound indexes are faster [source]
- The collection is very small (< 10k docs) and a $regex scan is fast enough [source]
- See the full SKILL.md at ~/.claude/skills/mongodb-atlas-search/SKILL.md for complete operator reference, analyzer tables, anti-patterns, scoring, facets, autocomplete, and search node guidance. [source]
