Inaccurate Search Bar

The Search Bar is what pops up when I press Ctrl+F right? and then I expect that what I type in there is exactly what will be searched for, but no, because apparently singular and plurals are the same thing to you or you really want me to manually search though 10k messages containing the word "light"(singular) to find that one message that was talking about “lights”(plural). TL;DR make text search have 0 margin and search EXACTLY what I typed in text wise
