Instead of adding additional search UI elements specific to the inventory list, allow composite search filters similar to the prefixes used by NEI/JEI and others.

For example (syntax made up for demonstration):

• +Alloy - highlights all Alloy Smelters, and righthand panel shows contents
• +Drawer coal - searches for coal in any inventory whose name contains 'Drawer'
• * diamond - searches for diamonds in all routable inventories
• -Drawer wood - search for wood in all inventories not named 'Drawer'

I'd expect +<keyword> to behave like a regular expression along the lines of /\w*keyword\w*/ (substring matching, so "Dr" =~ "Drawer"

Maybe also combined operators like:

• * +Chest -Iron bones - look in all routable chests except Iron Chests.

Further additions (@modname support, etc) are also desirable, but probably a separate feature.

Nice idea! Second this.
