Smart search - operators

Boolean operators

AND, OR, 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 patent documents where the words mouse and trap are less than three words apart in the TXT identifier .


Example: mouse prox/unit=sentence trap

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


Example: mouse prox/unit=paragraph trap

The system will find patent documents where the words mouse and trap happen to be in the same paragraph in the TXT identifier .


Comparison operators

Multiple terms to be searched within a specific field identifier should be surrounded by quotation marks. Everything within those quotes will be treated as a single search term and the order will be respected.

• =

Equal to

This is the default relation.

e.g. pa=siemens or ti="electric motor"

• all

All terms entered within quotes will be found within the field identifier, although perhaps not in the order in which they appear. All search terms between quotes are counted as one single term.

e.g. ti all "paint brush hair" is counted as one term.

• any

Any of the terms entered within quotes will be retrieved within the field identifier. When using the any operator, terms between quotes are counted as individual terms.

e.g. ti any "motor engine" is counted as two terms


Operators which are only valid for the publication date field identifier

• within

e.g. pd within "2005 2006" OR pd within "2005, 2006".

• >=

Greater than or equal to

e.g. pd >=2005 will retrieve documents having a publication date higher than or equal to 2005.

• <=

Less than or equal to

e.g. pd <=2005 will retrieve documents having a publication date less than or equal to 2005.
