I noticed something strange the other day and have just done some testing.
It appears that on iOS when I enter a string in the Library Find Resources box, the software checks for matches anywhere in the metadata associated with resources (title, description, etc). This is consistent with how the desktop app works.
On Android, it seems to apply a title: prefix so only resources with the search string in the title are shown.
I think it would be better - and more consistent - if the Android behaviour were changed to match the desktop and iOS apps
Thanks, Graham
