For instance, 'sans+geometric' will look for items containing both of those words individually-a smaller, more focused result-while 'sans,geometric' will return all items that contain either of those keywords-a much larger result. Now, adding a plus sign will return multiple single keywords, while adding a comma will match either keyword. For example, 'sans serif font' will not return 'sans' or 'sans-serif' but only items that have 'sans serif font' typed exactly. Until now, the system would only treat combinations of words, spaces and hyphens specifically. Though, I guess that wouldn't work if your planning on showcasing the world with said texture pack. Well, I can't help you with the texture pack part, but you can always use super secret settings and find the black and white or faded noir looking options.

My texture pack is a compilation of textures from numerous packs, edited by me. It has low fire, clear water, suitable for 1.7-1.8+ and does not give lag. It is a black and white themed default edit.
