Smart search operators

  • Boolean operators

    AND, OR and NOT are allowed. The default operator is AND. Left has precedence over right. No operator has precedence by default.

  • Proximity operators

    Example:mouse prox/distance<3 trap

    The system will find patents where the words mouse and trap are less than three words apart in the TXT identifier and in the order shown.

    Example: mouse prox/unit=sentence trap

    The system will find patents where the words mouse and trap happen to be in the same sentence in the TXT identifier

  • Comparison operators

    The terms to be searched within a specific field identifier should be surrounded by quotation marks.

  • =

    Equal to

    This is the default relation.

    Example: pa=siemens

  • all

    All terms entered within quotes will be found within the field identifier, although perhaps not in the order in which they appear.

    Example: ti all "paint brush hair"

  • any

    Any of the terms entered within quotes will be retrieved within the field identifier.

    Example: ti any "motor engine"

  • Operators which are only valid for the publication date field identifier

  • within

    Example pd within "2005 2006" or pd within "2005, 2006"

  • >=

    Greater than or equal to

    Example pd>=2005 will retrieve documents having a publication date later than or equal to 2005.

  • <=

    Less than or equal to

    Example: pd <=2005 will retrieve documents having a publication date earlier than or equal to 2005.
