SYMPTOMS
When you use a multi-word phrase in the Microsoft Windows Search feature to search for a file, the search may not return all the documents that match the search criteria.
CAUSE
This problem occurs because Search scans a document’s text in set sized blocks of words. If the phrase spans two blocks, Search cannot match the phrase. Search can only scan one block at a time, and Search does not carry over partial matches.
