If you have followed the egghead's suggestions you should now have a list of notes you've taken from various resources.
Organise your notes under your keywords. Write down the keywords you used to do your search, underneath write the notes that you think belong with that keyword.
Now you should be able to tell if you have all the information you need to write a well balanced answer from your notes.
If not you could think about other keywords and carry out another search with them.
