Now that we are able to visualize, version, and annotate your
Asset the next step would be able to explore your
DatasetVersion in an efficient way.
To do so, the best tool is the Search Bar and its associated Query language.
This Search Bar is accessible in each image overview of the Picsellia platform.
The Query language is used in the Search Bar to filter among
Annotations from the
It allows users to access all
Asset properties and sub-properties to search on them to find
Data satisfying the query.
As for now, we are dealing with the Search Bar available in the
Datalake, you will be able to search on all the objects and Metadata associated with Picsellia
Please note that in this list some fields are other Picsellia objects that are linked to Picsellia
Annotations. It means that from the
DatasetVersion Search Bar, you can go deeper into the Picsellia Object Schema to filter on
Data that are linked to another Picsellia Object.
For instance, we can retrieve all the
Asset from the
DatasetVersion that have a car annotated as a rectangle with this query:
annotations.rectangles.label.name = "car"
To browse through the Query langage across the Picsellia Object Schema, it is highly recommended to use the auto-completion proposed by the Search Bar.
In the end, the last element you are filtering on must be a property of either
Asset or of an object linked to
Depending on the format of the object property you are filtering on, several comparison signs are proposed by the auto-completion engine:
- For strings:
- For integers or floats:
In order to perform the most accurate filtering possible among your
Datalake, you can create complex queries leveraging the and & or logical connectors.
At the end of the first query element after leaving one space, the auto-completion engine will propose you the logical connector to your query.
After having written your query, you just need to press the Enter key to run the query. The
Asset from your
DatasetVersion satisfying the query will then be displayed.
To delete a query from the Search Bar
you just need to click the cross icon to the right of the Search Bar
It means that after having filtered through the Search Bar on your
Datalake, the only
Asset displayed in your Assets overview are the ones matching the query. The number of
Data matching is displayed on top of the
DatasetVersion as shown below:
