You may filter information by explicitly specifying the word(s) you are
seeking or a portion of the word. For example, entering %weed% will show all
plants with any portion of their name containing "weed" such as knapweed,
catchweed bedstraw, etc. Entering "Ambrosia%" will return anything in the
genus Ambrosia but if your spelling is questionanable you may enter %Ambro% and
achieve the same end.
