I agree with the others regarding better filtering although not with the suggested solutions. I think better filtering could be implemented from the creation side which would help in sorting/filtering on the viewing side.
While creating give check boxes indicating raids/raid-sections, if a BG which BG and even an "other" category for anything that doesn't fit the norm. Then when viewing I could limit my viewing window to a single raid or a small selection of raids (e.g. only SoO Flex 1 or ToT last two sections, SoO First 2 for those hunting for legendary quest items for instance) and I would *only* see those raids pop up.
If you create an easy to follow standard for premade creation the organization will extend to those searching for premades. Otherwise everyone has different methods for listing/creating their premade which makes searching and organization a pain on the viewing side. While something like wildcard searches seems to be a good stop-gap solution, I don't think it serves as a great overall solution to the current problem.
Keep up the good work and keep ignoring the haters like @kevinmd88
