yes,, it is difficult,, so I have made many product meta-data for serch cr2 files ^^;
actually sometimes I perfectly forgot the clothing which have no meta-data
but I have gotten already. then watch catarogue, throw the item again in my wishlist.
after that, when serch other clothings I may find my wishlist item is in my content tab^^;
it make me a little happy 
about some products, it has more pose file or material file that I did not notice.
and,, some items are made not one artist, so they make their own folda name for the same item.
poseworker>yourserch item> good pose
texturelover> yourserch item>beautiful texture
so I need keep all “read me” files in one folda, as wendy say,,
and just serch it by fle exprorer serch. actually I ofen rely read-me for serch content.
or make ” pruduct” meta-data then gather all files about the product, and set-meta data.
when you first install the items.
(it is not so exciting,, and if you missed compatibility setting you may perfectly forget the item,,
but,, it can help you to find your contents ^^; and if you feel happy your many product icon
show up in smart content tab! do not you feel so?!)
