hi.
so I finally managed to find a bit of time to get a SolR instance
going, and now have some questions about it ;-)
first the application is tagging. ie.. to associate some keywords
with a given item, and to show them on a particular object (you can
see this in action here http://economy-chat.com/aggy/detail/andrew-
leigh/ )
It user-based (ie individuals can tag a particular object themselves,
and that get's merged into a global summary for that object)
and it is also hierarchal, ie tagging a child implies you have also
tagged the parent.
so.. my first question in schema.xml, can you have a composite key as
the 'uniquekey' field, or do i need to do this on the client side?
2nd question.
can you have complex types which are multivalued?
I'd like to store something like
a tag-name with a corresponding tag-weighting.
can you do sum(*) type queries in lucene/solr? it is efficient ? or
are you better having a 2nd index which has these sum(*) values in it
and keep it up to date instead.
Thanks
