When all you have is search, you may run into the difficulty of actively organizing and structuring notes and clippings into a hierarchy, clusters, or mind map. Also the search support varies from "exact match" to "fuzzy match" to "synonym search".
For example, Evernote supports Notebooks but they only create one level of hierarchy. Often the use of "tags" is then recommended to label notes with context, hierarchy, and categories.
