indexing portal content by external search engine

Hi All,

I have a question about how to enable external search engine to index portal content.

as I searched in sap help [Indexing Portal Content|http://help.sap.com/saphelp_nw70ehp1/helpdata/en/46/9d1405fa743ef0e10000000a1553f7/frameset.htm]

To enable public search engines, such as Google, to index portal content, provide the search engine with the following URL:

irj/servlet/prt/portal/prtroot/com.sap.portal.utilities.tools.portalspider.SpiderWebInterface?

How should I provide this above url to external search engine?

Many thanks for all reply.

Cheers,

Kanok-on K.

P.S. We use the default KM.
