I did not know about that command. Thank you for letting me know. It still doesn't meet my request, but it is a good command to be aware of.
However, that command would be even more useful if it worked with the <link> feature. It would at least be useful for searching for certain gear sets. Does that command only work for one string, or can it look for items with multiple strings? For example "scylla's" and "casting," If I were searching for the casting set specifically.
