Currently, I assign an alias to items whenever I believe it would be useful to be reminded of their existence when I type the respective term in a note.
Sometimes this leads to duplicate aliases, but I set up the duplicate aliases script in a smart rule that alerts me when this is the case. So it gets remedied immediately by removing the alias from all but one of the items.
However, this is more often than not a forced choice. It would be preferable if the alias could remain on all of the items. Then I could, upon mentioning the term in a note, select one of the related resources e.g. by hovering over the wiki link, or via a popup menu.
