A lot of what I do is review notes and writing while annotating journal articles, summary, analysis and so forth. As I am compiling notes and reading summaries toward my comprehensive exams, I thought it would be nice to be able to read through my writing and highlight topics, themes, names, etc. that I could see being interconnected with other texts. It's less about searching but connecting.
