Ishan Chattopadhyaya created SOLR-11267:

             Summary: Add support for "add-distinct" atomic update operation
                 Key: SOLR-11267
             Project: Solr
          Issue Type: New Feature
      Security Level: Public (Default Security Level. Issues are Public)
            Reporter: Ishan Chattopadhyaya

Often, a multivalued field is used as a set of values. Since multivalued fields are more like
lists than sets, users do two consecutive operations, remove and add, to insert an element
into the field and also maintain the set's property of only having unique elements.

Proposing a new single operation, called "add-distinct" (which essentially means "add-if-doesn't
exist") for this.
