I am answering you in this topic to keep our discussion separate from the unrelated issues raised in the "Description field..." topic. Please respond in this topic.

thank you for the detailed answer. I'm sorry about the double post. Wasn't sure which one was the right one.
I guess the main issue we face is in the Media Manager Modal Window. Not being able to search for tags creates a big problem. We will literally have 10's of thousands of pictures and even filtering it down will not really help that much. So the only solution is to search for the images. But you can't search for tags but for descriptions and captions.
So my thought would be to bulk edit the description and caption (because we have lets say 10 images that have the same description/caption) so one could search for them in the Media Manager Modal Window. Or if there is a way to implement a search for tags in the Modal window.
The IPTC/EXIF mapping sounds interesting and I've looked at it. Am I right in the assumption one would need to bulk edit the IPTC/EXIF data offline so it would map when uploading them? Or is there a way to map the tags one bulk edits in MLA to the description and caption?
If you have some idea how to solve this problem I would appreciate it greatly. Thank you so much for your help.
I agree that searching on taxonomy terms such as Att.Tag is the right way to meet your requirements, and I am thinking about this for a future MLA version. In the interim you can use the IPTC/EXIF mapping to add tag information to one of the searchable fields.
Pick one of the Standard fields, e.g., Alternate Text, Caption or Description. On the Settings/Media Library Assistant IPTC/EXIF tab, enter something like this in the text box under the "EXIF/Template Value" column:
template:(tag values: [+terms:attachment_tag+])
This is a Content Template that will fill the Standard field with the literal "tag values: " followed by the Att. Tag values for any attachment that has them. If there are no tag values for a given attachment, no changes will be made to the Standard field.
Once the rule is in place, you can update all of your attachments by clicking the "Map All Attachments Now" buttons on the IPTC/EXIF tab. Since you have so many attachments, you might want to use the Bulk Edit area of the Media/Assistant screen, pick the attachments you want to update and use the "Map IPTC/EXIF metadata" button to map their values in smaller groups.
This is a crude solution to your requirements, but it may work for you. Let me know how it goes and if you have any further problems or questions.
