Powerpoint and Excel mimetypes missing "sub-class-of" information
The freedesktop.org.xml mimetype definitions need extra "sub-class-of" links for Microsoft formats such as ".ppt" and ".xls" The definition for ".doc" includes: <mime-type type="application/msword"> ... <sub-class-of type="application/x-ole-storage"/> ... which allows KDE free-text indexing (by baloo) to determine a file extractor. However the entries for ".ppt" and ".xls" do not include this subclass information, apparently Access files as well (although I'm not able to test this) Without the "sub-class-of", .ppt and .xls files are considered "application/x-ole-storage" and are not indexed. See: https://bugs.kde.org/show_bug.cgi?id=438455 with the pointer to the issue: https://bugs.kde.org/show_bug.cgi?id=438455#c23

The issue was originally identified on Neon Testing (above) but it also exists on Manjaro and Fedora 37 An override file with the subclass information added (for .ppt and .xls): https://bugs.kde.org/attachment.cgi?id=153934 Thanks to Stefan Brüns for the pointer...
