# 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` | One or more strings. A document returns only if one of `yourFields` contains a substring of one of the specified strings. You can match strings that contain punctuation (but see Note) or consist of several words. NOTE: Strings in the query must be percent-encoded to ensure that any commas or curly braces that are part of a string are not interpreted as query syntax. If you send HTTP requests using the content-type `application/x-www-form-urlencoded` you must then percent-encode all parameter values, meaning that any commas or curly braces that are part of a string are percent-encoded twice (such that a comma is represented by the sequence `%252c`). For more information, see Percent Encoding in Queries.
`yourFields` | One or more fields. A document returns only 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

The `SECTOR` field must contain a string that is a substring of `Telecommunications` or `Technology`. For example, if the `SECTOR` field has the value `Telecom` or `Tech`, the document returns. If the `SECTOR` field has the value `Latest Technology`, the document does not return.

    FieldText=SUBSTRING{scattering,doggedly}:ANIMAL

The `ANIMAL` field value must contain a substring of `scattering` or `doggedly`. For example, if the `ANIMAL` field has the value `cat` or `dog`, this document returns.
