# STRINGALL

The `STRINGALL` field specifier (case sensitive) allows you to specify one or more strings, which all 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 all these strings are substrings 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 `yourStrings` as substrings. Separate multiple fields with colons (`:`). There must be no space before or after a colon.

## Example

    FieldText=STRINGALL{cat,dog}:ANIMAL

The `ANIMAL` field value must contain the substrings `cat` and `dog`. For example, if the `ANIMAL` field has the value `grooming cats and dogs` or `doggedly scattering seeds`, the document returns.

    FieldText=STRINGALL{old cat,young dog}:ANIMAL:TOPIC

The `ANIMAL` or `TOPIC` field value must contain the substrings `old cat` and `young dog`. For example, if the `ANIMAL` field has the value `old cat chases young dog`, or `young.doggedly chasing bold cats`, the document returns.

    FieldText=STRINGALL{a%252Cb,e%252Cf}:MISC

The `MISC` field value must contain the substring `a,b` and `e,f`. For example, if the `MISC` field has the value `a,b,c,d,e,f` or `0=e,fx` `1=da,ba`, the document returns.
