The Cause:
With the introduction of the subtree search enhancements, a new field has been created in the search index, called "parents", which stores all the ascendants of a given class. Unfortunately, the side effect of this change is that a given term id now appears multiple times in many of the classes that are direct or indirect children of the given term. This bug affects only the searches by the term id. The exact pref label and synonym searches are unaffected.
