Major user search functionality improvement. This helps especially large installations with millions of users.

Breaking changes

Web themes

• Login layout has new error labels for username and password fields. They need to be added to any web themes that customise this view:
  

  // Add these after username and password fields
  <vaadin-label style-name="failure" plain-text _id="usernameErrorLabel" />
  <vaadin-label style-name="failure" plain-text _id="passwordErrorLabel" />

Technical notes

MongoDB text search index usage for user search was replaced with heuristic approach to search by interpreting the search input and building multi-key search query based on it. This can leverage MongoDB index intersection functionality for improved speed.

Group membership indexing was improved. This will cause some indexes to be rebuilt.
