For example, you could create a tag index on the hobbies
slot. The hobbies
slot of each entry would hold a symbol (like 'gardening
) or an array of symbols (like ['juggling, 'skydiving]
). Given this tag index, you could quickly retrieve, for example, those entries whose hobbies slot is exactly 'gardening
, or includes the 'gardening
symbol, or does not include 'juggling
.
