Entering queries

In the Smart search mask you can enter your query with or without field identifiers. When entering search terms you can use uppercase and lowercase letters.

Searching without field identifiers

The system will "guess" the field identifier (pd, ic, num, nm or txt) according to the following rules:



Field identifier

• yyyymmdd

• yyyy-mm-dd

• 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.

ic (international classification)

• ep

• nl19981010536

• ep1000000

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 (publication and/or priority and/or application)

• Apple

• Microsoft

• Smith

If the input starts with a capital letter followed by lower-case letters only, then it is a name.

nm (inventor or applicant or opponent or representative)

• motor

• engine

If the input starts with a lower-case letter, then it is a text.

txt (default identifier)

Example: Siemens EP 200701

The system will find documents having Siemens as the applicant, inventor, opponent or representative as well as EP as the publication number and 200701 as the publication date.

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"
