SUBSTRING

The SUBSTRING field specifier (case sensitive) allows you to return documents whose field value is a substring of a specified string (or equal to a specified strings).

Format

FieldText=SUBSTRING{yourStrings}:yourFields
yourStrings

Type one or more strings. A document is only returned if one of yourFields contains a substring of one of the specified strings. You can match strings that contain punctuation (but see Note below) or consist of several words.

NOTE:

To distinguish query syntax punctuation from punctuation within strings, double-percent-encode commas and curly braces within strings. Query syntax punctuation must be left unencoded. There must be no space before or after a separator comma.

yourFields Type one or more fields. A document is only returned if it contains one of these fields, and if the value in this field is a substring of yourStrings. Separate multiple fields with colons (:). There must be no space before or after a colon.

Example

FieldText=SUBSTRING{Telecommunications,Technology}:SECTOR

A document's SECTOR field must contain a string that is a substring of Telecommunications or Technology. If a document's SECTOR field, for example, has the value Telecom or Technology, the document is returned. If a document's SECTOR field has the value Latest Technology, the document is not returned.

FieldText=SUBSTRING{scattering,doggedly}:ANIMAL

A document's ANIMAL field value must contain a substring of scattering or doggedly for this document to be returned. If a document's ANIMAL field, for example, has the value cat or dog, this document is returned.
