Is your feature request related to a problem? Please describe.

When I clean my bags after questing, raiding, or doing dungeons, I use the bag search to filter out specific items for my mule characters. After nine (9) expansions, items saved in bags are numbered in the extreme and so I send various items to various characters based on my own sense of sorting. Some bag searches work in Blizzard's bag search but NOT in Bagnon, while others do work. Examples:
'resto' matches items like 'Bone Apple Tea' where it says 'Use: Restores 40,000 mana over 20 sec.' where all items without this text will be greyed out for easy identification and selection. This works in Blizzard's bag search, but NOT in Bagnon.
'equipp' matches new items that are 'Binds when equipped' like new green, blue, or purple quality items where all items without this text will be greyed out for easy identification and selection. This works in Blizzard's bag search, but NOT in Bagnon.
'soulb' matches items that are 'Soulbound' in my bags for easily identifying all old items where all items without this text will be greyed out for easy selection. This works in Blizzard's bag search and in Bagnon.
'craft' matches items with the text 'Crafting Reagent' in my bags for easily identifying all crafting items where all items without this text will be greyed out for easy selection. This works in Blizzard's bag search and in Bagnon.

Describe the solution you'd like
Filtering for each of the above items is great when it works. Currently, I am unloading Bagnon and then reloading the UI to gain the search functions and then reloading Bagnon with another reload of the UI to get Bagnon back. Adding the missing searchable text of items would fix this problem.

Describe alternatives you've considered
As a programmer, I know there's a better feature I can suggest: how about setting up (similar to Equipment Manager) profiles to either automatically highlight specific types of items (one for new BoE items, one for restorative drinks, one for about every searchable item type available, etc.) and assign them to a button -or- a profile for item types for email with email integration.

Additional context
Add any other context or screenshots about the feature request here.

I would like to add, all 'tags' on items all work as search terms in Blizzard Bag Search but not in Bagnon search.

Things like "Naval Equipment" on the item "Ice Cutter" [or other Draenor Garrison Shipyard equipment], or "Cypher Equipment" on the Zereth Mortis gear, etc.

However, I would like to point to the search wiki Bagnon has:
https://github.com/tullamods/Wildpants/wiki
https://github.com/tullamods/Wildpants/wiki/Frequently-Asked-Quentions

Which points to the search library Bagnon uses, see here:
https://github.com/Jaliborc/LibItemSearch-1.2/wiki/Search-Syntax

So, doing a search of tooltips like "tt:cypher" will show these tags. I would suggest seeing if any of the listed things there can help you in your searches, @respect1st

Tooltip searching is extremely expensive, and there's no other way for addons to search items locally. Blizzard search is done on their servers, without needing to compute and display invisible tooltips to search.
