API Description

You can query and count files in a dataset based on extracted file metadata, including fields such as filename, tag, path, custom tag, and text. Logical expressions are supported.

Authorization Description

When using a sub-account, add the ci:DatasetSimpleQuery permission to the action of the authorization policy. For all operations supported by Cloud Infinite, see CI action.

Use Limits

Before using search, complete creating a dataset first.
Only the Jakarta region is supported. In the request Host, Region can only be set to ap-jakarta.
For more usage limitations, see Usage Limits.

Request Parameters

Parameter Name
Description
Type
Required
DatasetName
Dataset name, unique within the same account. You can query it through the console or API
String
Yes
Query
Simple query parameter conditions that can be nested
Container
No
Sort
List of sort fields. For details, see Scalar Search Expression Syntax
Multiple sort fields can be separated by half-width commas (,), for example: Size,Filename
You can set up to 5 sort fields
The order of sort fields determines their priority
String
No
Order
Sort order of the sort fields. Valid values:
asc: Ascending
desc (default): Descending
Specify the rule information as follows:
Multiple sort methods can be separated by half-width commas (,), for example: asc,desc
The number of sort methods cannot exceed the number of sort fields. In other words, the number of elements in the Order parameter must be less than or equal to the number of elements in the Sort parameter. For example, if Sort is set to Size,Filename, Order can be asc,desc or asc
If the number of sort methods is less than the number of sort fields, the unspecified fields default to asc. For example, if Sort is set to Size,Filename and Order is set to asc, Filename defaults to asc, which means ascending order
String
No
MaxResults
Maximum number of file metadata entries to return
Valid values range from 0 to 200
When aggregate parameters are used, this value indicates the maximum number of groups to return, with a valid range of 0 - 2000
If this parameter is not set or is set to 0, the default value 100 is used
Integer
No
NextToken
token used for pagination when the total number of binding relationships exceeds the specified MaxResults
Returns the list of binding relationship information in lexicographic order starting from NextToken
Set this parameter to null when you call this API for the first time
String
No
Aggregations
List of aggregation field information
When you use aggregation queries, only aggregated results are returned, and the list of matched metadata is not returned
Container Array
No
WithFields
Returns only the values of specified fields instead of all existing metadata fields
Can be used to reduce the size of the returned structure
If this parameter is not specified or is left empty, all fields are returned
String Array
No
Query node content:
Parameter Name
Description
Type
Required
Operation
Operation operator. Enum values:
not: logical negation
or: logical OR
and: logical AND
lt: less than

gt: greater than
gte: greater than or equal to
eq: equal to
exist: existence query
prefix: prefix query
match-phrase: string match query
String
Yes
SubQueries
Structure for subqueries
Subquery conditions can be set only when Operations is a logical operator (and, or, not).
When the logical operator is and/or/not, all conditions described in its SubQueries must conform to the and/or/not logical relationship set by the parent
Container Array
No
Field
Field name. For supported fields, see Scalar Search Expression Syntax
String
No
Value
Field value to query. When Operations is a logical operator (and, or, not), this field is invalid
String
No
Aggregations node content:
Parameter Name
Description
Type
Required
Field
Field name. For supported fields, see Scalar Search Expression Syntax
String
No
Operation
Operator for aggregating fields. Enum values:
min: minimum value
max: maximum value
