Good news for GIF fans: Tumblr has introduced a new search feature. Where before users were only able to search the reblogging site using tags, they're now able to search for words, tags, or even multiple tags.
Search for "dog GIFs," for example, and you'll find all posts that mention dog GIFs in their body or tag. Search #dog GIFs and you'll find only those tagged as such. Look for #cool #dog GIFs, and you'll only see posts tagged with both tags. The search will also show you related blogs, and a new filter means posts can be filtered by type. The explicit content filter, too, has been moved to make it easier to see and use. The new search function is available now, but you'll need to log in to a Tumblr account to use it.
