requested to merge issue/migrate_plus-3229479:3229479-entitylookup-taxonomyterm-restricted into 6.0.x
Update EntityLookup.php, it allows a restriction based on a vocabulary VID. Such restriction is necessary if the same item(string/word) is found in two vocabularies and the we only care about the result from one of them.
Closes #3229479
