Under what circumstances would it be appropriate to use the sentence method of note taking, and what are the advantages and disadvantages of this method?

The sentence method is writing every new thought as an individual sentence. The advantage of this is that it is much easier to go back and find where a specific topic's notes are as opposed to having to read through a paragraph of notes. The disadvantage of it is that it's harder to convey a deeper meaning when every thought is written in its own line.
