Searchable Logger: Independent Handlers and Keyword Index

Repair independent log handlers, add keyword search, and combine indexed matches without losing record identity.

The scenario

Repair independent log handlers, add keyword search, and combine indexed matches without losing record identity.

A failure to reason about

Use a small stateful services and indexing scenario to compare current behavior with the requirement.

Illustrative context for the topic. The exercise’s full requirements arrive in the workspace.

Questions to bring to your review

  • Which caller makes the reported behavior visible?
  • What focused regression would distinguish the current behavior from the requirement?
  • What existing behavior must remain intact after the change?

Skills you will practice

  • Object-oriented design
  • State ownership
  • Inverted indexes
  • Record identity
  • Testing

Read the existing code, reproduce the reported behavior, review proposed changes, and verify your final implementation. You can use AI assistance while staying responsible for the result.
