Hi,
Holger, thank you, I will try your suggestion.
However, I use MongoDB 3.4, and I think that Voyage has support for only
versions under 3.0. Am I right?
Stef, collection in mongo is a container for documents. For example, here
three documents are inserted in collection "inventory":
db.inventory.insertMany([
{ item: "journal", qty: 25, tags: ["blank", "red"], size: { h: 14, w:
21, uom: "cm" } },
{ item: "mat", qty: 85, tags: ["gray"], size: { h: 27.9, w: 35.5, uom:
"cm" } },
{ item: "mousepad", qty: 25, tags: ["gel", "blue"], size: { h: 19, w:
22.85, uom: "cm" } }
])
