This is one of those things that is, IMO, strictly a "feel good" thing that's sometimes insisted upon by the product manager and all the information in the world about "this is really meaningless" falls on deaf ears. If you simply have no choice (a position I've been because it wasn't worth the ar

Honeslty the only case where the score in percentage could make sense, is for the More Like This. In that case Solr should provide that feature as we perfectly know that the 100 % similar score is a copy of the seed document. If I am right, because of the MLT implementation, not taking care of the

Currently I've take the score that I get from Solr, and divide it by the maxScore, and multiply it by 100 to get the percentage. All these are done on the coding for the UI. The user will only see the percentage and will not know anything about the score. Since the score by itself is meaningless, s

We want the user to see how relevant the result is with respect to the search query entered, and not how "good" the results are. But I suspect a problem is that the 1st record will always be 100%, regardless of what is the score, as the 1st record score will always be equals to the maxScore. Regar

The question is more why do you want your users to see the scores? If they are wanting to affect ranking, what you want is the ability to run the same query with different boosting and see the difference (2 result sets), then see if the new ordering is better or worse. What the actual/raw score i

Correct. The relevancy score simply states that we think result #1 is more relevant than result #2. It doesn't say that #1 is relevant. The score doesn't have any validity across queries either, as, for example, a different number of query terms will cause the score to change. Upayavira On Tue,

Hi Arslan, Thank you for the link. That means we are not advisable to show anything that's related to the relevancy score, even though the default sorting of the result is by relevancy score? Since showing the raw relevancy score does not make any sense to the user since they won't understand what

Hi, Would like to check, does the new version of Solr allows this function of display the relevancy score in percentage? I understand from the older version that it is not able to, and the only way is to take the highest score and use that as 100%, and calculate other percentage from that number (
