Opensolr Changelog — Recent Updates & Improvements

Web Crawler Mar 7, 2026

New Bulk query deletion in Query Analytics — select multiple queries with checkboxes and delete them in one click. Available on the Queries, No Results, and Click Analytics tabs. Useful for cleaning out junk, test queries, or inappropriate search terms from your analytics history.
New Click Analytics with CTR tracking — see which search results users actually click. Three views in the new Click Analytics tab: Top Clicked documents, By Query with click-through rates, and Low CTR to find queries where users search but never click. All click data is IP-deduplicated and rate-limited to prevent bot noise.
New No-Results Dashboard — a new tab in Query Analytics that tracks every search returning zero results. Each zero-result query is counted by unique IP (not raw page views), so the numbers reflect real users, not refreshes. Use it to spot content gaps, missing synonyms, or pages your crawler hasn't reached yet.

New Clear button on Crawl Stats for 4xx and 5xx errors. Click Clear next to Client Errors or Server Errors to delete those entries from the crawl database. Useful for cleaning up old 404s before resuming a crawl so they get retried on the next run.
New New Renderer setting in the Web Crawler. Choose between Curl (Fast) — the default, fetching pages in ~0.2s each — and Chrome (JS Rendering) for JavaScript SPAs like React, Vue, or Angular where content is rendered client-side. Chrome runs every page through a headless Chromium browser. Available in the UI dropdown and the REST API (renderer parameter), and persists across cron restarts.

New Sitemap re-discovery on Resume. When you resume a finished crawl, the crawler now re-fetches all XML sitemaps — not just the top-level sitemap index, but every child sitemap too (e.g. sitemap-products1.xml through sitemap-products22.xml). Any new URLs found in those sitemaps get queued and crawled automatically. This means your index stays up to date as your site adds new pages, without needing a full re-crawl.

New New Pause and Resume controls for the Web Crawler. You can now temporarily pause a running crawl without losing your cron schedule — the crawler will automatically pick back up on the next scheduled tick, or you can hit Resume to restart it immediately. The Stop button has been renamed to Stop Cron Schedule to make it clear that it permanently removes the schedule.
