Search within a dataset

With the search bar, you can search for samples by their name, metadata attributes, and label content.

Search by metadata attributes and label content

Search syntax

To search by sample name, just type the full or partial name of a sample.

To search by metadata attribute, use the key:value syntax.

To search by number of objects of a category in a labelset, use the labelset.category:=value syntax, or labelset.total_count:=value to search by total number of objects.

To search by labeler and reviewer of a sample, use the labeled-by:username or reviewed-by:username syntax.

For string values, use the : operator. For numeric values, use the operators :=,:>, :>=, :< and :<= to search for values that are equal to, greater than, greater than or equal to, less than, and less than or equal to another value. For list values, use the :| operator to search for a value contained in the list.

Queries can be combined by separating them with a space. They will be ANDed together.

Search from label statistics

On the Overview tab, you can click a category name in the label statistics to jump to the Samples tab.

The search bar is pre-filled with the corresponding category query.

The current search query is also reflected in the page URL through the ?q= query parameter. For example, ?q=ground-truth.category:>0 opens the Samples tab with that filter already applied.

This makes filtered views easy to bookmark and share. The search input and URL stay in sync in both directions: typing in the search bar updates the URL, and opening or editing a URL with ?q= updates the search field.

Examples

Examples
image_grayscale matches samples with the word "image_grayscale" in their name.
city:london matches samples with a metadata attribute "city" set to "london".
vehicle_id:>3 matches samples with a metadata attribute "vehicle_id" set to a value larger than 3.
ground-truth.car:>=5 matches samples where the "ground-truth" label contains 5 or more "car" objects.
my-predictions.car:<5 matches samples where the "my-predictions" label contains less than 5 "car" objects.
my-predictions.total_count:<=20 matches samples where the "my-predictions" label contains 20 or fewer objects in total.
city:london ground-truth.car:>0 my-predictions.car:=0 matches samples where metadata attribute "city" is set to "london" AND the "ground-truth" label contains more than 0 "car" objects AND the "my-predictions" label contains 0 "car" objects.
tags:|red matches samples where metadata attribute "tags" is a list of values ["red", "green", "blue"].
