Well, first click on lookup items.
Type in Schematic for all engineering recipes, and pattern for tailoring (and whatever else uses patterns) recipes. This will work for engineering, but tailoring, i am not sure about.
Edit: On the items menu to the left, click advance search. At item type, scroll down and select tailoring or engineering.
This will give you a list of all recipes not learned from a trainer. This is handy for looking for missing recipes.
