You receive inconsistent search results when you search for content that contains a particular Chinese Traditional term in SharePoint Portal Server 2003 or in SharePoint Server 2007

When you search a Microsoft Office SharePoint Portal Server 2003 or a Microsoft Office SharePoint Server 2007 portal site for content that contains a particular Chinese Traditional term, you receive unexpected and inconsistent search results. The first time that you search for content that contains a particular term, some documents that contain that term are missing from the search results. The next time that you search for content by using that same term, you receive a different set of search results. For example, more documents that contain that term are returned in the search results.

This problem occurs if the information that is learned by the Chinese Traditional word breaker in SharePoint Portal Server 2003 or in SharePoint Server 2007 is not retained. The Chinese Traditional word breaker uses a dynamic learning method to break words in the content index that the word breaker is not familiar with. The Chinese Traditional word breaker component uses the dynamic learning method to process words when content is crawled and when content is queried.

This problem was first fixed in a hotfix that is now contained in a service pack. If you installed the latest SharePoint Portal Server 2003 service pack, you do not have to install the hotfix.

For SharePoint Server 2007, no hotfix is required. But the DisableDynamicLearning registry entry must be added following the steps in the "Add the DisableDynamicLearning registry entry" section.
