    /DIR="x:\dirname"

    /SharepointDefault "https://sharepoint.com/sites/mySite"

    /AADApplicationID 12345678-1234-1234-1234-123456789012
| Specifies the application ID to use when using SharePoint search with multi-factor authentication (MFA).
    /AADRedirectURI myapp://auth

    /DefaultIndexServerName "<server name>"

    /IndexServerCertificateThumbprint "<thumbprint>"
| Use this parameter to specify a thumbprint of a certificate that UltraSearch should trust when communicating with the DataCentral server. Note This thumbprint can be obtained from the Options dialog of SpaceObServer (“Options > System > index Service”). Tip You can pass “none” to this parameter as well, or even leave the value blank. In this case UltraSearch will only trust valid certificates with a trusted certificate chain.
    /IndexServerCertificate "<full path pfx-file>"
| Specifies the full path to a certificate file (pfx-file) which should be installed and used for the communication with the DataCentral server.
    /IndexServerCertificatePassword <password>
| In case the pfx-file specified with parameter /IndexServerCertificate is protected by a password, use this parameter to specify the password. Note Use this parameter only in combination with /IndexServerCertificate.
    /IndexServerAcceptAnyCertificate <True/False>
| Use this parameter and pass True in case you want to accept any certificate when communicating with the DataCentral server. Note We do not recommend using this option as this type of communication represents a potential security vulnerability!
