- Add a general item -
Let's enter an item of general information and see how it will connect
automatically to one of the items in the shopping list. Here we
go: title - "lentils nutrition facts", tags - "lentils, nutrition",
body:
per 1/4 cup:
dietary fiber, 14g, 56% dv
protein 13g
calcium 2%
iron 2%
folate 50%
magnesium 12%

Let's filter by the tag "lentils"—you should see the shopping list
item and the last item we entered. Go ahead and add a diary entry:
title - "lentils", tags - "diary, lentils", body - "today I found out
something curious about lentils—they have the highest protein
content of any plant food after soybeans and hemp, and they were one
of the first crops domesticated in the Near East in Neolithic times."
When you save this item, it should show up in the current list of
items (which is refreshed after each save). You will now have three
items of completely different "main" categories that will show up
when you search for lentils (actually, no category has more weight
than others in Tobu, although you can use an additional tag to
specify which category is the main one and sort by that tag, but that
would be an overkill in most cases). If you are a nutritional scientist
or an agronomist you may end up having thousands of entries under
"lentils" and then you might prefer to add a second and third filters
to suit your current scope of interest—for the rest of us,
filtering by one tag alone will be enough to locate this item.
