Basic Rules For Optimal Searching
ORto get more results. Example:
cat OR dog(content contains either "cat" or "dog").
ANDto require all words, but this is the same as the default behavior. Example:
cat AND dog(same as cat dog, content must contain both "cat" and "dog").
-to exclude them; you must still have at least one "positive" keyword. Example:
at -dog(content must contain cat and cannot contain dog).
