Or what is probably a better idea is to use another word with "liar" and forget "lies". How about "deceitful"?

This search finds 197 remedies but when we look at the results we see that there are many references to "deception" and "deceive" that often do not refer to being deceitful.

In this case we want to search for the exact word "deceitful"; to do that we put an exclamation point after the word. (An exclamation point says "use only this exact word".)

This finds 112 remedies and almost all references are correct!
