This plugin replaces the default database search with Elasticsearch, providing a high-performance search engine for content-driven sites. It is designed for developers and site administrators who need faster, more accurate search results and the ability to handle complex queries at scale.

• Direct Elasticsearch Integration: Syncs post content, metadata, and taxonomies to an Elasticsearch index, allowing all site searches to be executed against the external engine.
• Controlled Meta Indexing: Post meta fields are indexed only when explicitly configured, improving performance and preventing bloated indices. Supports specific data types like strings, booleans, numbers, and dates.
• WP-CLI and Admin Tools: Includes a WP-CLI command for efficient bulk indexing of large sites and provides an administrative interface for managing the connection and indexing status.
• Query and Filter Support: Enables advanced search features like faceted filtering and search-as-you-type suggestions by leveraging Elasticsearch's full query DSL through custom PHP classes.
• Backward Compatibility Focus: Maintains compatibility across multiple major versions of Elasticsearch, with detailed release notes for any required breaking changes.
