Server based Search- Exact match and Prefix match in Lync Server 2010

Server based Search- Exact match and Prefix match in Lync Server 2010

Guys,

We are using Lync Serer 2010 since long however you know how the server based search is work? Here are few scenarios; basically Server-based search usage can be configured by using the in-band provisioning setting, AbsUsage.

This in-band provisioning setting having three possible values:

1.    WebSearchAndFileDownload. IP phones (for example, Polycom CX700 IP desk phone) use server-based search, and Lync 2010 clients use GAL download. This is the default.

The Lync desktop client defaults to GAL download for the following reasons:

·       There may be temporary outages for the Address Book Service depending on the server maintenance schedule. When the Address Book Server is unavailable, all prefix and exact match searches fail.

·       Server-based search does not work in branch office resiliency mode.

2.    WebSearchOnly. Both IP phones and Lync 2010 clients use Server-based search.

3.    FileDownloadOnly. Both IP phones and Lync 2010 clients use GAL download.

Server-based search can be used for both exact and prefix searches. The exact and prefix match searches are different, and the various scenarios when the Lync client would perform an exact match search versus prefix match search.

The Lync client sends a SOAP query through HTTPs to the user’s Front End pool. Search results are returned in an XML format.

Exact Match Search

Exact match search is performed by the Lync client whenever it needs GAL contact data for a specific contact. In an exact match query, the Lync client requests the GAL contact data by using a SIP URL or email address. Passing a SIP URL or email address in the request ensures the GAL contact data returned is unique because the SIP URI and email address are both unique contact identifiers.

Prefix Match Search

Prefix search is invoked when a user initiates a search from the following:

·       The main UI search box.

·       The People picker dialog box (that can be opened, for instance, from the Conversation Window, the call forwarding dialog box, or call transfer).

When a prefix search is performed, the client sends a SOAP query with the search term and number of search results to be returned by the Address Book Service. Lync client shows the top 50 results whereas IP phones and Lync mobile clients show the top 20 results.

Thank you.

2.                 Expand ComputerName (local computer), expand Web Sites, right-click the website that hosts the address book, and then click Properties.

3.                 Click the Directory Security tab.

4.                 In the Secure communications section, determine whether View Certificate is enabled.

If the certificate is invalid, follow these steps:

a.     Click Server Certificate in the WebSiteName Properties dialog box.

b.     Click Next, and then click Renew the current certificate. Or, click Replace the current certificate.

c.      Follow the steps to finish the IIS Certificate Wizard.

Note The IIS Certificate Wizard will help you renew your certificate or replace your certificate with a valid certificate.

a.     Click Server Certificate in the WebSiteName Properties dialog box.

b.     Click Next, and then click Create a new certificate.

c.      Follow the steps to finish the IIS Certificate Wizard.

In Windows Server 2008, make sure that the website that is hosting the address book has a valid SSL certificate installed. To do this, follow these steps:

2.                 Expand ComputerName (local computer), expand Web Sites, click the website that hosts the address book, and then click Bindings in the Actions pane.

3.                 Select the HTTPS site binding that includes the port that the Address book Service is listening on, and then click Edit.

4.                 Click View to open the certificate dialog box, and then view the expiration date of the certificate on the General tab.

Note The IIS Server Certificate feature helps you renew your certificate or replace your certificate with a valid certificate.

•          If the certificate is invalid, follow these steps:

a.     In the Connections pane, select the name of the IIS 7.0 server that hosts the Address Book service, select the Features view, and then click Server Certificates.

b.     In the Actions pane, select Open Feature.

c.      In the Features view, select the certificate that you viewed in step 4, and then use the Actions pane to renew the certificate.

•          If the needed certificate is not installed on this computer, use the certificate wizards in the Actions pane to do one of the following: Import, Create a Certificate Request, Complete a Certificate Request, or Create a Domain Certificate.

Thank you.
