For multi-valued fields, you can use "add" to add a value to the list. If the value already exists, it will be there twice.
"set" will replace the entire list with the one value that you specify. There's currently no method to remove a value, although the issue has been logged: https://issues.apache.org/jira/browse/SOLR-3862 You can always edit the list by pulling down all the values and uploading the new set.
