[Find similar words if needed] helps you to find different forms of a word (error, different writings and so on) if the original word could not be found. With [Always show similar words too] you will get this feature regardless whether the original word was found or not.
[Wildcards] using * are allowed at the beginning, at the end and even in the middle of a word. Example: info* for information or infotainment.
Using [Boolean Operators], AND is the predefined operation between two words. Moreover, you can use OR and NOT.
