Search currently only returns five matching tags, regardless of how many there are. This means that when there are more than five tags that start with the same string of characters, some results will never be discoverable unless you already know the whole tag or else brute force by just typing different letters.
For example, currently there are many different tags starting with "The Cohost Global Feed (...", presumably most of which are shitposts, but it would still be nice to be able to see them all without having to search
"The Cohost Global Feed (a"
"The Cohost Global Feed (b"
"The Cohost Global Feed (c"
