Opensolr Search
Opensolr Search replaces WordPress’s default search with a powerful, hosted Apache Solr search engine. It combines traditional keyword search with AI-powered vector search for dramatically better relevance. Key Features: Hybrid Search — combines keyword matching (BM25) with semantic vector search (1024-dim embeddings) for the best of both worlds Faceted Navigation — filter results by category, price range, date, custom fields, and hierarchical taxonomies AI Hints — streaming AI-generated answers above search results, powered by RAG AI Reader — full-screen AI summary of any search result Autocomplete — real-time search suggestions with query history and Solr results WooCommerce Support — index products with prices, categories, SKUs, and structured data Two Indexing Methods — Web Crawler (automatic) and Data Ingestion API (push from WordPress) Search Analytics — track queries, clicks, CTR, no-results queries, and visitor patterns Query Elevation — pin or exclude specific results for any query Persistent Filters — admin-defined include/exclude filters applied to every search Multilingual — automatic locale filtering for WPML and Polylang sites Dark Theme — built-in dark mode for the search page Embeddable — use native search or embed the Opensolr hosted search widget How It Works: Sign up at opensolr.com and get your API key Install the plugin and enter your credentials Create a search index or connect to an existing one Configure your sitemap and start the web crawler Your search page is live at /opensolr-search The plugin generates a complete sitemap, injects meta tags for the crawler to extract, and provides a full search experience with zero load on your WordPress server — all search queries go directly to the Opensolr cloud. Requirements: An Opensolr account (free tier available) PHP 8.1 or higher WordPress 6.0 or higher External services This plugin depends on several online services operated by Opensolr (https://opensolr.com) to provide hosted search. You must have an Opensolr account; all indexing and search queries flow through these services. The service is required for core plugin functionality and cannot be self-hosted. Service provider Opensolr — hosted Solr search cloud and AI API Privacy policy: https://opensolr.com/learn/privacy-policy Terms of service: https://opensolr.com/learn/terms-of-service Account signup (free tier available): https://opensolr.com/register Endpoints the plugin contacts https://opensolr.com/solr_manager/api/* — account management, index create/reload, config upload, sitemap registration, elevation toggle, crawl start/stop/stats. Called from WordPress admin (not from visitors’ browsers). https://api.opensolr.com/solr_manager/api/ingest — Data Ingestion API: pushes your post content + metadata to the search index. Called from the WordPress site (cron worker and the real-time sync on post save/delete), never from visitors. https://api.opensolr.com/solr_manager/api/embed — generates a 1024-dim semantic embedding for the current search query (AI/hybrid search path only). Called from the WordPress site on every AI/hybrid search. https://api.opensolr.com/solr_manager/api/embed_and_search — finds the documents in your own index that an AI Hints answer should be based on. Called from the WordPress site only when the admin has enabled AI Hints. https://api.opensolr.com/solr_manager/api/ai_summary — streams the AI Hints / AI Reader answer. Called from the WordPress site only when the admin has enabled those features. https:// .solrcluster.com/solr/ /select — the Solr search request itself (host provided by Opensolr when you create an index). Called from the WordPress site on every search. https://search.opensolr.com/embed.js — loaded ONLY if the admin switches Search Mode to “Embeddable”. In Native mode (the default), this script is never loaded. Data sent to these services Your Opensolr email + API key (authentication). Your site’s host name (meta_domain). For ingestion: post titles, content, URL, excerpt, author display name, taxonomy terms, publish dates, WooCommerce price + category + SKU, featured-image URL. Only for the post types you explicitly enable in the plugin settings. Never includes user login data, email addresses, or passwords. For search: the search query string, the active facet filters, pagination position. For AI features (when enabled): the search query, plus the text of the top 4 matching documents from your own index, so the AI can compose an answer grounded in your content. This is your own already-indexed content being sent back for the answer — nothing new is collected from visitors. For click tracking (when enabled): the clicked result URL, title, position, the search query, and a SHA-256 hash of the visitor’s IP (never the raw IP). Analytics can be disabled from the plugin’s Search Display settings. No data is shared with any third party — all traffic goes only to opensolr.com / api.opensolr.com / *.solrcluster.com (and only to search.opensolr.com if you explicitly enable Embeddable mode).
