I have shelves and shelves of RPG books, and a lot of it's D&D. I have every Dungeon magazine from #1 on. But for some reason I can never find the right adventure for what I need.
What I'm thinking of is a database where I can search on the adventures mainly by level and by relevant tags.
I've found a couple online DBs like the Dungeon Magazine Index, but they usually don't allow useful searching, and they don't let you multiselect. Like I'm not picky about whether an adventure is for 3e, 3.5e, or Pathfinder, but usually they don't let you search on that. And poor data entry is a problem; like searching for level 5 doesn't match "4-6". And it should search on extended attributes or even user-added tags - if an adventure is set in Greyhawk in an Egyptian-themed pyramid tomb in a desert and has undead and stuff, it would be tagged "greyhawk egyptian pyramid undead mummy desert". Ideally it would include "Official" (WotC/Paizo), third party/OGL, and Dungeon mag stuff, from all editions.
Like my current use case is "I want an adventure for 5th level PCs. I'm running Pathfinder, but 3.5e/3e are OK. I'm interested in it having one or more of the following attributes - pirates, urban, horror, flooding, shadow." I basically have to rack my memory, leaf through my shelf of published modules, and eye the shelf of Dungeon magazines and sigh.
What databases/tools exist that might allow this?
