== Overview ==In standard !GeoNetwork search results can be ordered by relevance. This is based on the relevance score that the Lucene search engine gives to each item in the search results. However it is not shown to the user what the relevance score for each result *is* or how they compare between each other.[[BR]][[BR]]

== Proposal == 
In standard !GeoNetwork search results can be ordered by relevance. This is based on the relevance score that the Lucene search engine gives to each item in the search results. However it is not shown to the user what the relevance score for each result *is*.[[BR]]
In [http://nationaalgeoregister.nl NGR] the relevance score is displayed with each search result. Because the Lucene score is an unattractive float between 0 and 1, the relevance score is normalized such that the highest score from the search results is set to 100, and all other results' scores are calculated relative to that.[[BR]][[BR]]
