Let me know when you found a way! Never really tried to do so... Not necessarily...
I started categorizing them from the very first day I started gathering materials and stuff...
Stored them in categorized folders and in different text and PDF files... Just like the Jargon topic...
When looking for some idiom or proverb I just open the related .txt and type the idiom in Persian or English... Always got the result I wanted so far... Never fails...
I actually don't really need them anymore... I mostly remember everything...
