What Is the Difference between Explicit and Dynamic Parameters?

Explicit parameters apply to all sources indexed using the connector—for this reason, they are created directly in the Modify Additional Connector page. They are used to input information common to all repositories (ex.: the username and password required to access databases). You can see and modify explicit parameters in the Connectors page for a specific connector (see Adding an Explicit Connector Parameter).

Dynamic parameters apply to a single source and are created in the Add Source page. They are used to adapt indexing to a specific repository (see Adding a Dynamic Parameter to a Connector Source).
