When looking for multiple words the default is to AND together each word. Searching for big dog is the same as big AND dog.
You can combine multiple words together with the OR statement. For example: dog OR cat
Multiple character wildcard searches looks for 0 or more characters. For example:
test* or te*tThe single character wildcard search looks for terms that match that with the single character replaced. For example:
te?tNote: You cannot use a * or ? symbol as the first character of a search.
For example dog NOT hound would find any dog as long as it was not a hound dog.
