^,A caret signifies the start of a line. For example\, filtering search terms by ^megalytic would match any instances where megalytic was the first word in the search term.
$,A dollar sign signifies the end of the line. For example\, filtering search terms by megalytic$ would match any instances where megalytic was the last word in the search term.
|,A vertical pipe essentially means “or.” For example\, filtering sources by google|bing would match instances of either google or bing.
.,A dot matches any single character except for a line break. For example\, filtering by megal.tic would match instances of either megalytic or a misspelling like megalitic.
\ ,A backslash “escapes” the character following it. For example\, when entering a URL\, should you place a backslash in front of the period\, it would ensure it’s treated not as a wildcard but as part of the text string\, as in megalytic\.com.
*,A star matches zero or more of the previous character. For example\, megalyt*ic would match megalytic\, megalyttic\, or megalytttttttic.
