When performing string searches in BitBucket, as described at https://confluence.atlassian.com/bitbucketserver/bitbucket-search-syntax-814204781.html, the search results would be a long list of files depending on the scope (Modifiers).  In this case, it's hard to make the search results useful without the ability to export the results to csv or other form for analysis.
