Login integration (OAuth) is on by default. Under 인증 공급자 선택 (Select authentication provider), choose Keycloak to sign in directly with your PaaS account (SSO).

If you connect Elasticsearch in the connection items at install time, search integration is set up automatically. There is nothing to configure in the Wiki.js admin screen.
| What search covers | |

| Without Elasticsearch | Title · description |
| With Elasticsearch | Title · description · body |

Korean words are matched by partial text too. Searching 회의 also finds documents containing 회의록.
