This is exactly my point.  The Title field should be irrelevant when searching on other criteria.  One should be able to construct a Search based on the other fields.  

For example, if you get the listings up for Stamps>Europe>France and Colonies and then apply the filters Region:'French Cameroon' and Item Location: 'UK only' you will not see any of my listings - despite the fact that they are listed under the Region category as French Cameroon.  The Search facility is using the Title field and not the Region field.  My lots under French Cameroon all start the Title field with Cameroon and so they are not being retrieved by Search.  This is clearly wrong, in that the Search is not operating on the appropriate fields.
