Hi, I have a question regarding function query that operates on multi-value fields. For the following field:
<field name=rgbcolor type="string" indexed="true" stored="true" multivalued="true"/> Each value is a hex string representation of RGB value. for example there are 3 values indexed #FF00FF - C1 #EE82EE - C2 #DA70D6 - C3 How would I write a function query that operates on all values of the field? Given color S in query, how to calculate the similarities between S and C1/C2/C3 and find which one is the closest? I checked https://lucene.apache.org/solr/guide/6_6/function-queries.html but didn't see an example. Thanks, Wei
