It is difficult to organize folders and pages so that the "All Pages" navigation makes sense and for the search bar to return meaningful results.
I think showing a page's subtitle next to the page title in the search results would help out a lot, in terms of making sure a user doesn't have to select multiple search results to find the information he/she is looking for.
Example repo structure:
If my subtitles for the two different categories are "Basic instructions for Feature 1" and "Advanced topics for Feature 1", showing those subtitles in the search results will help me choose which article I want. I won't need to open both pages to see which pages is the most relevant for me.
Suggested search result format:
<b><page title></b> - <i><page subtitle></i>
