About this parameter
Controls the relevancy threshold below which less relevant results aren’t included in the results.
Usage notes
relevancyStrictnessis available on applications having the Relevant sort feature enabled.- You can set 
relevancyStrictnesson virtual replicas only. relevancyStrictnessisn’t supported for browse.- The value must be an integer between 0 and 100 (inclusive).
 
By default, this parameter is set to 100, which is the maximum value to offer a relevant sort. If this behavior isn’t suited for you and to know what value works best for your use-case, you can:
- Test your top queries with different values of 
relevancyStrictnessuntil you’re satisfied with the balance between the relevancy of results and the number of returned hits. - If you have enough traffic on your sort, you can start an A/B test to test different values of 
relevancyStrictnessand see which one works best. 
Options
 | 
      The default value of   |

      Returns hits with 90% similarity as compared to the most relevant hit.  |

      From the attributes that you list in the Relevant sort   |
