Change in the behavior of “is not” and “does not contain” filters

Tags

1. Context

As part of the continuous improvement of the platform, we are evolving the behavior of the following filters:

  • “is not”
  • “does not contain”

This change applies across all environments:

  • Administration platform
  • Mobile application
  • Studio (automatic selections, manual selections, display conditions, etc.)
📅

Release date

  • Planned deployment: week of April 16, 2026
  • Target version: 1.174.0

2. Current behavior

Today, when using the following filters:

  • “is not”
  • “does not contain”

👉 Empty fields are excluded from the results

This means that if a value is not filled in, it is not taken into account in the filtering.

3. New behavior

With the upcoming update:

👉 Empty fields will be included in the results

Concretely, a non-filled value will be considered as matching the filters:

  • “is not”
  • “does not contain”

4. Objective of this change

This update aims to:

  • Standardize filter behavior,
  • Improve functional clarity,
  • Make results more intuitive.

5. Potential impact

This change may impact your usage if you rely on these filters in:

  • Your custom views,
  • Your searches,
  • Your Studio configurations:
    • Automatic selections
    • Manual selections
    • Display conditions

As a result, your filters may return more results than before.

6. Recommended actions

We recommend that you:

  • Audit your existing configurations
  • Identify where “is not” / “does not contain” filters are used
  • Anticipate any necessary adjustments
