Search is not returning pages that have not been updated recently

Issue Summary

Confluence Cloud Search is not returning pages that haven't been updated recently.

Steps to Reproduce

1. Make sure there's a page that hasn't been updated recently (previous than the last month, for example)
2. Search for that page 

Expected Results

All pages that a user has permission to view should return in the search, even if it wasn't updated recently.

Actual Results

Not all pages that a user has permission to view are returning in the search because pages that haven't been updated recently aren't being listed in the search results. 

Workaround

Currently, a workaround would be to add a label to the page that isn't returning in the search and then remove the label.
