Elasticsearch 8.10 introduces query rules, a feature that allows for the customization of search results based on query terms or contextual information. This innovation enables users to tailor search outcomes for marketing campaigns, personalization, or segment-specific results by implementing pinned query rules, which prioritize certain documents in search results based on defined criteria. Supported criteria for matching include exact, fuzzy, prefix, and suffix matches, among others. Administrators can create and manage these query rules via the query rules management API, storing them within Elasticsearch and applying them during searches to rewrite queries into pinned queries, which then prioritize specified documents. An example use case involves a global e-commerce site promoting different versions of a wireless charger based on the user's location, ensuring the most relevant product is featured prominently in search results. This capability is part of the broader suite of features in Elastic 8.10, offering users enhanced control over search result customization.
