Elasticsearch Integration
Semantic and vector search for WordPress - replace default search with Elasticsearch-powered relevance
Elasticsearch Integration replaces the default WordPress search with a purpose-built Elasticsearch engine that understands what your readers are looking for - not just the keywords they type. Semantic search, vector search, faceted filtering, and real-time indexing turn your site search from a liability into a feature readers actually use. In production deployment, this plugin delivered a 30% improvement in search relevance metrics, measured by click-through rates on search results and reduction in zero-result queries. When readers find what they need on the first search, they stay longer, read more, and come back.

Features
Semantic Search
Queries are interpreted by meaning, not just keyword matching. A search for "climate policy impact" returns articles about environmental regulation effects, carbon pricing outcomes, and sustainability legislation - even if those exact words never appear together.
Vector Search
Content is indexed as vector embeddings alongside traditional text indices. Vector search finds conceptually related content that keyword matching misses entirely, surfacing relevant articles from your archive that readers would never have found otherwise.
Faceted Filtering
Search results include dynamic filters - by category, date range, author, content type, and custom taxonomies. Readers narrow results without re-searching, and facet counts update in real time as filters are applied.
Real-Time Indexing
New and updated content is indexed within seconds of publication. No waiting for nightly re-index jobs. The plugin hooks into WordPress save actions and pushes changes to Elasticsearch immediately.
Search Analytics
Track what readers search for, which results they click, and where searches return zero results. The analytics dashboard surfaces content gaps and popular topics - data that drives editorial planning.
Custom Ranking
Control how results are scored. Boost recent content, prioritize specific categories, weight by author authority, or apply custom scoring functions. Ranking rules are configurable per search context without touching code.
