Roberto,

Thanks for the documentation update. I think it still needs some work, as I 
am still not understanding how to make a smart link. The explanation is 
becoming a little clearer, but the documentation needs a lot more detail to 
help someone else build their own smart links.

Do you mean - 
"Use smart links if you need to reference a *document type* from another 
*document 
type* and they are not from the same index. " This is very different than 
"...reference a *document* from another *document*." 

I would like to use one *document type*, (say *photo* - a collection of 
photos), and have two *indices* describing that photo. Say the *subject* of 
the photo and the *year* the photo was taken. I would then want to link all 
the photos taken in 1970 with the same subject. I assume from the above 
statement, that this is not a smart link, and it is probably not possible 
to achieve with Mayan. Is that correct?

Since indices are related to metadata, I think the real question is how do 
I relate two metadata fields on one document type? 

document type = photos
metatdata 1 = decade the photo was taken
metadata 2 = subject of the photo

How do I get a search result that says here are all the photos taken in the 
1840s that show a gun fight?

Is that possible with Mayan?
