When I search the gallery for lots, I almost always am searching with the hash tag for whatever the original lot name was for where I'm planning to put it. That and #NoCC are pretty much the only hash tags I ever pay attention to for lots.
Those hashtags, the images provided, and the lot type are all that matter to me. I don't read the rest of what people put in their description, to be honest.
For pictures, I like to have a good look at what the lot looks like both inside and out so I can see if it looks 'basic' or actually like a real place would. By basic i mean little to no decor and clutter and boring and boxy for the overall design.
For Sim/Household downloads, I never actually search for those other than EA Pre-made makeovers, but again I care about the #NOCC hashtag. I don't download any Sims/Households other than pre-made makeovers except those that show up in my feed as being created by or favorited by someone I follow. Not because I don't download sims...but rather because I already have over 1000 sim households downloaded from the gallery, so I don't see a need to actively search for more.
