Here are tips for better search results in databases. This usage works on most databases, but check 'Help' sections for supported search syntax.
Boolean: (using operators: and, or, not)
mother AND father searches for occurrences of both words within scope defined.
mother OR father searches for one or all, but both are not required.
mother NOT father searches for occurrences of the word ‘mother’ without use of the word ‘father.’
(mother NOT father) AND god searches for occurrences of the word ‘mother’ without use of the word ‘father,’ then also requires the word ‘god.’
art* (asterisk as truncation character) searches for art, arts, artistic, artful, etc.
m?n (question mark as wildcard character) searches for man and men.
