If we were to spend more time on the LOTRO site's database adding filters to more easily find things like items would be one of the first things we'd do. However, LOTRO is a smaller game and fairly low priority, so I don't know if we'll add any more enhancements to it in the future or not.
I've wanted to make the searches more like EQ2 (my first real project working for Zam was the EQ2 overhaul,) since almost the time I first saw them; even not playing the game, I wanted it as a pet project. As Jerek mentioned, unfortunately, the traffic LOTRO gets just can't justify the time to do it right now. However, I'm definitely pulling for cleaning up the *list pages when we eventually have the time. Thanks for the feedback, and sorry we can't give a more precise/positive answer at this time.
