Introduction

Before AI Search writes an answer, it looks for matching content on your website. The Retrieval confidence threshold decides how good a match must be before AI Search uses it.
  • Higher value – stricter. Fewer made-up or off-topic answers, but more “no answer found”.
  • Lower value – more answers, but some may use content that fits less well.
The default 0.62 works for most websites.

​
Change the value

  1. Go to AI Universe → AI Foundation → AI Features.
  2. Open the Training card.
  3. Enter a value between 0.40 and 0.90 in Retrieval confidence threshold.
  4. Save.
  5. Clear all caches.
  6. Test a few searches.

You don’t need to train your content again after changing this value.

Tuning guide

AI Search gives every match from your content a score. It answers from your content only if the best score reaches the threshold.
  • Setting key: retrievalConfidenceThreshold (from 0.40 to 0.90, default 0.62).
  • The score of a match is the higher of two values: how similar it is to the question, and its search ranking.
  • A match that contains a word from the question can also pass with a lower score (at least 0.45).
