If you consistently click to use the autocomplete choice, it's possible that the first time you did that there was some minor - possibly "invisible" - error in what the browser suggested so that you're actually consistently repeating the same corrupt search term.

The filter should return every thread name that includes whatever you type, and sometimes it's best to NOT try to put the entire title in. If I type just the four letters tatt and set to one year I find three threads, two up above and yours down in BS, and it's easy to pick the right one.

The thread names returned must contain the characters you enter, but must exactly match what you type, but it should return all the threads that contain exactly that character sequence along with anybunchofotherstuff. The more characters you enter, the more likely what you type will include an error that isn't in any thread title.

Typing "tattered" or "tatte" or "tatt" works, but "tat tered" doesn't, and with some fonts a random space is hard to see, and/or rn looks like m, etc. The autocomplete/autosuggest will generally "recommend" something you have typed recently. Doing it wrong once likely will return the same error as long as you "click to complete" your entry instead of typing all of the term you want to use each time - or at least once after the filter didn't find what (you thought) you asked for.
