typing "lifecycle" in documentation Search box should list the Screen Activation Lifecycle

Expected:

When one types "lifecycle" in documentation Search box the results should include the Screen Activation Lifecycle.

Result:

Screen Activation Lifecycle is not listed. (It is found on the Cheat Sheet under "Routing".)

Start by reproducing the documentation Search box query for "lifecycle" and inspect how documentation pages are indexed. The work is done when the Screen Activation Lifecycle appears in those results, while existing search behavior remains intact.
