Hi Jim
Thanks for the response. I have built a .Net API to manage manual indexes. So
basically when I create a node I have an option to parse in a collection of

However it sounds like auto indexing might be a better option? I avoid
simple one to one non composite values??

Tatham has also added support for paging queries, so queries returning more
