It took me ten seconds to write the reply to help out a fellow Anki learner in the Facebook group, so it doesn't normally warrant a post, but I couldn't think of a more perfect scenario for explaining why knowing even a little regex can be a life-saver sometimes. In this case, one wants to search for a word like "lit" and does not want to see words like "little" in the search results. In other words, you would check the "whole word" or "exact" search option. But Anki does not have this option per se. This is where regex comes in. One can achieve the same purpose by using the \b anchor in regex:
