Office SharePoint Server Search keeps results to itself

Instead of some information I'm posting a question today..

We've build an application that uses the search functionality to roll up content. Only not all content gets returned in the way you would expect it to.

A description of the problem can be found here:

Any suggestions as to what's happening are greatly appreciated.

We found the solution!

The problem was caused by the TrimDuplicates function. Even though the content articles that were rolled up weren't the same at all, SharePoint thought they were, so most of them were filtered out because the TrimDuplicates property is set to true by default. After setting the property to false all results were returned as expected.

hi,

i've got a similar problem.

But i've got an additional question: how do i set the TrimDuplicates function to false for the default Search Webpart?

If you use a default Search Results web part you can change the setting by following these steps:

* Go to the Search Center page

* Click on Site Actions and on Edit Page

* Click on the web part context menu

* Click on the Modify Shared Web Part link

* Open the Results Query Options

* The top option is now Remove Duplicate Results. This is checked by default. Uncheck it and press OK.

This should solve your problem by simply using the MOSS UI.

hi Mirjam,

thanks for your reply.

I've tried it out - just didn't saw the option before.

But until now it seems to me, that the results are removed when crawling.

I've got a list with about 550 items of content type "feature". But when searching for this property or using it as search scope it only gives me 512 items as result.

Do you have any idea about this behaviour?

Greetings,

Johannes
