The SharePoint item being crawled returned an error when requesting data from the web service.

When using FAST search for SharePoint 2010 (F4SP) to crawl a content source that contains managed metadata in the field you might get this error

The SharePoint item being crawled returned an error when requesting data from the web service. ( Error from SharePoint site: *** Index was outside the bounds of the array. )

this is because one or more metadata field is filled with incorrect value. When you open it up it show something like this.

The red underline text means there's no term "Knowledge" in the Knowledge Themes metadata field.

if you leave this red text save in your item properties and run a crawling. You will get this error.

To solve this error

That's simple, correct the red underlined text in metadata field. then FAST search will crawl this item correctly.

FAST Search Managed Metadata Problem

I've got a Problem with the number of Managed properties doesn't correct because of multiple value in crawled properties mapped with managed properties.

the results should be 249 for Content Types and at least 249 for Project Type because Project Type properties in mandatory field and allow multiple value. the the sum of Project type is just 230. There's something wrong with the managed properties, I though. Finally, I found the solution. Many thanks to the following links and Google. http://fs4sp.blogspot.com/2011/04/multi-valued-managed-properties-as.html http://blogs.pointbridge.com/Blogs/tseng_william/Pages/Post.aspx?_ID=14 http://msdn.microsoft.com/en-us/library/ff625183.aspx http://technet.microsoft.com/en-us/library/ff393811.aspx I didn't map the ows_projecttype() with my managed properties ProjectType.

After mapped with the correct crawl properties and rerun full crawl. it works.
