The Search Tuning tab decides how results are ranked on your search page. The defaults suit most sites. Changes apply to the next search, with no crawl or ingestion needed. Each control below links to the page that explains it in depth.
Field Weights
How much a match in each part of a page counts: Title (0.1 by default), Description (0.03), URI (0.01), Text (0.01) and LD Text, the text of the page's structured data (0.03). Each takes a value from 0.01 to 999.99. Field weights
Semantic ↔ Lexical Balance
A slider from 0.10, where meaning counts most, to 1.00, where only the words count. 0.50 by default. It matters on searches with AI on. Balance between meaning and words
Minimum Match
How many of the searched words a result must contain: Flexible, Balanced (the default), Strict, or Custom with your own rule, for example 2<90% 5<75%. Minimum match
Search Mode
How words and meaning are combined on searches with AI on:
- Union (default): a result matches by words or by meaning.
- KW Required: the words must match, meaning adds to the score.
- Meaning Req.: the meaning must match, words add to the score.
- Intersection: both must match.
- Lexical Only: words only, for every search. The AI switch is hidden from visitors.
Vector Candidate Pool
How many results found by meaning are considered before the final ranking, from 10 to 1,000. 500 by default. More is more thorough and a little slower. Vector candidate pool
Content Quality Boost
Rewards pages with rich content and holds back thin ones, from Off to Maximum (0 to 1.00). 0.30 by default. Quality boost
Fresh Results Bias Weight
How hard the visitor's Fresh switch pushes newer content up, from Subtle to Newest first (0 to 1.0). 0.5 by default. It does nothing until a visitor turns Fresh on. Fresh results
Save or reset
Click Save Tuning. Reset All to Defaults, at the bottom, puts every control back to the values above after a confirmation.
