In the event that legal discovery is requested against Confluence Cloud instances, The search is not reliable enough to extract documents that pertain to the legal discovery, and does not provide a bulk export of the search results documents.

To resolve this I would like to recommend two things:
1. Provide a more comprehensive set of advanced search options that will allow for exact string matches in search (regardless of search time)
2. Provide bulk export of search results Documents in full with an option to include document versions.
