Smart search - entering queries

In the Smart search mask you can enter your query with or without field identifiers.


Searching without field identifiers

The system will "guess" the field identifier (pd, num, ia, txt and cl) according to the following rules:


Input

Description

Field identifier

• yyyymmdd

• yyyy-mm-dd

• dd/mm/yyyy

• dd.mm.yyyy

If the input conforms to one of these formats, then it is a date.

pd (publication date)

• H01M5/12

• B03

If the input conforms to the classification symbol pattern, then it is a classification.

cl (classification)

• EP

• FR3

• MXPA01007454

If the input consists of two (or three or four) letters, followed by a sequence of digits, followed by a letter and/or a digit, then it is a number.

num

• Apple

• Microsoft

• Smith

If the input starts with a capital letter and then contains only lowercase letters, then it is a name.

ia (inventor and applicant)

• motor

• engine

If none of the above items work, then it is a text.

txt (title, abstract, inventor and applicant)

Example: Siemens 1978783

The system will find documents having Siemens as the applicant or inventor as well as 1978783 as the publication, application or priority number.


If you surround a group of terms with quotation marks, everything within those quotes will be treated as a single search term and the order will be respected.

Example: "laser scanning microscope"

The terms which you wish to search within a specific field identifier should be surrounded by quotation marks.


The query is read from left to right.


Examples:


ti="electric motor"

ti any "motor engine"

ti all "paint brush hair"


The Smart search mask lets you use proximity operators as well as comparison operators (e.g. any, within, all). For more information have a look at the help file on Smart search - operators .
