Filter Entities

How to filter results on entities API

You can filter the results of your API requests to refine the set of entities you want to obtain and limit the volume of data transferred between the backend and your application.

GoodData utilizes RSQL to define filters on the entities API. Only a subset of RSQL is supported, and we add our operators to make some queries easier.

Create a filter

Filter the API call result using URI parameter filter as follows:

.../api/v1/entities/...[?&]filter=<RSQL>

where <RSQL> is the RSQL query consisting of <property><operator><arguments>;:

  • property is an attribute of the queried entity
  • operator is one of the supported logical or comparison operators
  • argument represents the filtered value in form related to comparison operator

Example

Fetch only visualizationObjects that use a metric with the word ‘sale’ in the metrics title:

.../api/v1/entities/workspaces/{workspaceId}/visualizationObjects?filter=metrics.title=containsic='sale';

Note that this example uses the containsic operator which is the case-insensitive variation of the contains operator. See below for a complete list of supported operators.

Limitations

Following limitations apply:

  • You can filter only results of the entities APIs /api/v1/entities/.... Declarative APIs do not support filtering.
  • Ensure the filtered string is properly url encoded. For example, wrap values containing a whitespace character with single or doubles quotes and apply url encoding to the entire value.
  • Queries are case-sensitive in general. There are GoodData specific operators allowing case-insensitive queries.

Operators

Logical operators

To filter for multiple properties at the same time, use the AND logical operator:

  • Logical AND: and or ;

    Example: Filter entities with specified title and tag ‘Sales’. Using the and operator and url encoded value:

    filter=title=like=*date+and+tags==Sales
    

    or using the ; operator:

    filter=title=like=*date;tags==Sales
    

Comparison operators

The following subset of RSQL comparison operators is available:

  • Equal to: ==

    Example: Filter entities having tag ‘Sales’:

    filter=tags==Sales
    
  • Not equal to: !=

    Example: Filter entities not having tag ‘Sales’:

    filter=tags!=Sales
    
  • In: =in=

    Example: Filter entities having one of the specified tags ‘PreSales’ or ‘PostSales’:

    filter=tags=in=(PreSales,PostSales)
    

    See grouping.

  • Not in: =out=

    Example: Filter entities which do not have at least one of the specified tags ‘PreSales’ or ‘PostSales’:

    filter=tags=out=(PreSales,PostSales)
    

    See grouping.

  • Case-sensitive contains: =contains=

    Example: Filter entities having a tag containing only substring ‘sales’:

    filter=contains==sales
    
  • Case-insensitive contains: =containsic=

    Example: Filter entities having a tag containing a substring ‘sales’ regardless on the case sensitivity:

    filter=containsic==sales
    
  • Pattern search: =like=

    • * to capture a group of characters
    • ? to capture exactly one character

    Example: Filter entities having a tag starting with letter P and ending with substring Sales:

    filter=tags=like=P*Sales
    

Filtering via relationships

You can filter by a property from a referenced entity in case two entities are in a relationship. You have to specify the relationship property before the property you are going to filter (an extended form of the property): <relationship-property-name>.<property-of-related-entity>

Example

Filter only visualizationObjects having relation to metrics with a title ‘quantities’:

.../api/v1/entities/workspaces/{workspaceId}/visualizationObjects?filter=metrics.title==quantities

Grouping

To create a list / group of items to filter use grouping operator () and separate items with , or or - for example (PreSales,PostSales) or (PreSales or PostSales).
