Too many ‘Contains’ operators cause segments to work incorrectly

Last update: Wed Jun 18 2025 00:00:00 GMT+0000 (Coordinated Universal Time)

This article provides a workaround to the Adobe Analytics issue where too many Contains operators cause segments to work incorrectly.

Description description

Environment

Adobe Analytics

Issue/Symptoms

The Contains related operators are the most processing-intensive features in segmentation, as these analyze the entire content of every value. Using hundreds of Contains operators in segments prevent the segments from working correctly.

  • contains
  • does not contain
  • contains all of
  • does not contain all of
  • contains any of
  • does not contain any of

For more information, refer to our documentation on Comparison Operators for Segments.

Resolution resolution

If you have many segment conditions (for example, Page equals X, Page equals Y, or Page equals Z repeated with hundreds of different values), follow the workaround below:

  1. Create segments separately for one hundred different values per segment.
  2. Use classifications to group dimension items. Instead of writing out hundreds of conditions, classify all desired values into a classified value, then use the classified value in a segment.

Also, refer to Segmentation best practices for details.
