Thanks Paul,

Here's another question.
Let's say i expand the "isa" property to contain an array...

{
   "_id": "tweety",
    "isa": ["bird", "pet", "target"],
   "_rev": "3-d085e60568133d80a96cd735c6c306f6",
   "color": "Yellow",
   "nemesis": "Sylvester"
}

And say all my docs have various "isa" (or tags) values.. does this mean I
need to put the values in specific order and know this order in advance to
find them? ie:
http://127.0.0.1:5984/dbname/_design/ddocid/_view/view_name?key=["bird",
"pet" "target"]
