Hi Alex
A common example is to use a doc.type field in each doc; here I have
locations & contacts in the same DB;
{
"_id": "DEU.Berlin",
"type": "location",
"country": "DEU",
"city": "Berlin",
"address": "Speedbone Internet & Connectivity GmbH\nAlboin
Kontor\nAlboinstr. 36-42\n12103 Berlin"
}
{
"_id": "d...@example.org",
"type": "contact",
"location": "NZL.Wellington",
"phone": "+64 4 9727208",
"fax": "+64 4 9727123",
"name": "Dave Cottlehuber"
}
and then they can be filtered/split separately in views with a map/reduce;
function(doc) {
if (doc.type == "location") {
emit(doc.location, doc.type ) }
};
