• If you are trying to use Boolean operators, they must be ALL CAPS: (((("design intelligent surveillance camera") OR ("designing intelligent surveillance over"))) OR ((("decision intelligence surveillance cameras") OR ("decision intelligence surveillance chapter")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"design intelligent surveillance camera\") or (\"designing intelligent surveillance over\"))) or (((\"decision intelligence surveillance cameras\") OR (\"decision intelligence surveillance chapter\"))))".
• Removing quotes may allow a broader search: (((( design intelligent surveillance camera ) or ( designing intelligent surveillance over ))) or ((( decision intelligence surveillance cameras ) OR ( decision intelligence surveillance chapter )))).
• Adding a wildcard symbol may retrieve word variants: (((("design intelligent surveillance camera") or ("designing intelligent surveillance over"))) or ((("decision intelligence surveillance cameras") OR ("decision intelligence surveillance chapter"))))*.
