Thanks Cletus, I have my structure set up as you've noted.
I've been working with this more and am still not seeing what I expected. I need to clarify my question.
Under the Keyword Tags box in the right column, there are 2 choices in the drop down box. 1) Enter Keywords and 2) Keywords & Containing keywords Will Export. If 2) is selected, then the field goes dark gray, (data cannot be entered) and when a bottom level keyword (Oriole) is selected from the keyword list all the upper level Hierarchial keywords show up.
When 1) is selected, the field is white and allows direct entry of keywords or entry by selection from the key word list (selecting the check box). By doing the latter, the only word that shows up in the Keyword Tag field is the actual selected keyword itself (Oriole), with no parents.
At this point, since only the lowest level keyword shows up in the tag field, does that mean that it is the only one one applied to that image for internal searching by LR2?
I'm unsure what the 2) selection keyword tag drop down box does. Since all the decending parents show up (but are in a gray field), does that mean that they are applied to the image as it exists in LR2 (and thus searchable) or does that mean that they will only be applied to the metadata if the image is exported (meaning not searchable from within LR2)?
I'm still not sure I've explained this correctly. What I am after, is to be able to select only the lowest level word in the nested hierarchy and have all the above words (parents) be applied also, and show up in the tag field and be searchable through LR2.
Thanks
