Thank you for this answer. This behaviour of the Organizer defies (my) logic. Why on earth does the Organizer show me items that do not match my tag selection ? The point of tagging and selecting images by tag should be to allow filtering of the images in the database and suppress items that do not match without my having to additionally select "Hide items that do not match"  as an Option. Or have I misunderstood something here ?

P.S  When I click on Options it shows me "Show results that do not match (9261)". When I click on that the unwanted thumbnails that do not match disappear, i.e. exactly the opposite of what the menu option promises. If I then click on "Hide results that do not match (9261)" it shows me the thumbnails that do not match. The toggle seems to be working in a sense opposite to the correct/expected one. P.

Thanks again. Yes, it's 9.0.3.

The search I attempted was very specific in that I have tagged all my images and I searched for specific images by double-clicking on the tag on the right of the Organizer screen. I wasn't attempting anything fuzzy or otherwise smart.

Aaah ! Got it. So, since computer menu items conventionally show the action that will be executed if the user clicks on that item or show a tick box next to an item like this that can be toggled, the problem here is that the menu item is counterintuitively designed (in the Windows and Linux worlds that I work in). It simply needs a tick box next to it as in this example from my browser options.

Thanks again.

To come back to the original problem, with "Hide results that do not match" set I still get large numbers of thumbnails that do not match the tag I'm filtering for.

I cannot find anything which would explain these mis-hits apart from the fact that they are photos taken around the same time. I've fiddled with the 'Options/Hide best match' criteria without success.

How can I force the PSE9 organizer to simply show me the photos tagged with the tag I check ?
