Hi, The limit is actually 5000, and refers to the index entries per entity. Index entries depend only on the contents of the entity, not on entities that reference it. For example, an entity with 3 non-list indexed properties 'foo', 'bar', 'baz' would have 3 index entries. If 'foo' was a 5 element list, it would have a total of 8 index entries. If bar was also a 5 element list, it would have 11 index entries - and so forth.
