Extending OpenSearch: A Practical Guide To Building Custom Plugins
summary
Six concrete plugins with code on GitHub: a smart ASCIIfolding rules analyzer that preserves accents for specified words (fixes French edge cases), an ingest lookup processor that enriches product docs with price/stock from other indices at index time, and an autocomplete system that builds a separate autocomplete category index for low-latency (target ~5ms) completions. Also included are a query-relaxing endpoint that runs sequential fallback queries, a search-as-you-type query shortcut, and a synonyms index plus Dashboards UI — all demos run and code shown.
