# STRING

The `STRING` field specifier (case sensitive) allows you to specify one or more strings of which one must be contained as a substring in a specified field.

NOTE: The field specifier speed can be optimized by restricting the field to the property type.

## Format

    FieldText=STRING{yourStrings}:yourFields

`yourStrings` | One or more strings. A document returns only if one of these strings is a substring of the value in one of `yourFields`. 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 contains one of `yourStrings` as a substring.Separate multiple fields with colons (`:`). There must be no space before or after a colon.

## Example

    FieldText=STRING{cat,dog}:ANIMAL

The `ANIMAL` field value must contain the substring `cat` or `dog`.

    FieldText=STRING{old cat}:ANIMAL:TOPIC

The `ANIMAL` or `TOPIC` field value must contain the substring `old cat`. For example if the `ANIMAL` field has the value `old cat`, `old caterpillar` or `bold cats`, the document returns.

    FieldText=STRING{example.com}:COMPANY

The `COMPANY` field value must contain the substring example.com. For example, if the `COMPANY` field has the value `example.com` or `http://www.example.com/content/home`, the document returns.

    FieldText=STRING{a%252Cb}:MISC

The `MISC` field value must contain the substring `a,b`. For example, if the `MISC` field has the value `a,b` or `a,b,c,` the document returns.
