The problem is not on the side of Phex as the searching client but on the other replying Gnutella servents.
Usually servents should only return search results if all terms match but some bad behaving clients like Morpheus or different search algorithms are also returning on partial matches, 2/3 matches or 3/4 matches. Also words with less then 3 or 4 characters might be ignored by some clients.

You can refine your search results inside Phex using the filters. Define a filter with words that must be part of the search result and define a media type and maybe a min file size. This can help you to eliminate the noise in your search results.
