Hi, I suspect the tag you searched for is a business term under a taxonomy, and not a regular tag. If yes, this behavior can be explained.
It is a by-product of how business terms are implemented today. AFAIK, they are implemented as traits. For regular traits (or tags), new instances are created whenever they are associated with an entity. However, terms are 'singleton' traits, i.e only one instance is created and this is looked up and associated with entities whenever the term association happens. The singleton instance is attached to the 'Taxonomy' instance by the Business Taxonomy implementation as a way of easily looking it up when required for association. The side effect of this, is that when we search for a business term - because it is a tag, the search API gets both objects (the actual association and the implicit Taxonomy object association) in the results. You must not see this behavior for regular tags.
