Note that Lucene doesn't support general in-place document updates, and updating a document means first deleting it and adding it back.
Therefore if you only intend to add/change few categories of an existing document, you have to fully re-index the document. This is not specific to categories but applies for any field that you add, except NumericDocValues fields which support in-place document updates since Lucene 4.6.
