Search Tuning is a panel in the settings of your Opensolr Index. It decides how your site search ranks results: how much meaning counts against exact words, which part of a page matters most, how many of the search words a page must contain, and a few switches for quality, freshness and the results page.
There are no configuration files to edit. Every change is saved the moment you make it, and there is no Save button.
Where to find it
- Open your Opensolr Index in the Control Panel.
- Click the WebCrawler tab.
- In the Quick Access bar, click Settings.
- In Index Settings, click Search Tuning to open it.
The WebCrawler tab is there for every index in a region with site search: What your index needs.
What it changes
- The hosted search page of your index, on search.opensolr.com or embedded in your site.
- Searches your own code makes through the Opensolr search API.
- The searches the chat bot makes in your index.
The Drupal module and the WordPress plugin have their own Search Tuning screen for their search pages: Drupal, WordPress.
Where each control acts
The controls
In the order they appear in the panel:
- Semantic ↔ Lexical Balance: how much exact words count against meaning.
- Field Weights: which part of a page counts most.
- Minimum Match: how many of the search words a page must contain.
- Search Mode: which pages can appear, word matches, meaning matches or both.
- Vector Candidate Pool: how many pages each side of the search brings in before ranking.
- Content Quality Boost: rich pages up, thin pages down.
- Fresh Results Bias Weight: how strongly the visitor's Fresh switch favours new pages.
- Results Per Page: how many results the search page shows at a time.
- Show Documents Search: Web and Documents tabs on the search page, or web only.
Semantic ↔ Lexical Balance, Search Mode and Vector Candidate Pool work on meaning, so they appear when your index can use AI search: What it uses from your plan.

Reset All to Defaults, at the bottom of the panel, puts every control back to its default after you confirm.
