As already mentioned two days ago every good website should have an option to search the content of the site. Although MCMS does not ship it's own search engine you can easily integrated 3rd party search engines with MCMS. Especially to integrate with the Search engine from SharePoint Portal Server Microsoft ships controls with Connector for SharePoint Technologies.
But honestly: I have never heard from a customer that he is satisfied with these controls as they do not allow any customization. Neither the look-and-feel nor the information being returned can be customized.
For prototyping these controls are ok but not to use them on most production sites. So you would need to implement your own search controls.
A good start for this are the search controls provided by Stephen Huen. He has implemented search controls as well in C# and in VB.NET
Do you know much about the free mcms search available from Snow Valley? I need to implement a search option for my mcms 2002 website but we don't have the funding for Sharepoint. I need to come up with a solution and can't think of anything.
I'd really appreciate your help.
I haven't used it myself - but the overall feedback from the community was good.
If it fits your requirements is something you would need to evaluate yourself.
