Hi,

Currently, my document structure looks something like this:

{  
"localizedStr" : [  
{"en-us" : "someValue"},  
{"es-es" : "algunValor"},  
....  
]  
}

I have explicitly included in my mapping every possible culture-locale that  
we currently support. My fear is that when we add more to the system, I  
have to update my mapping.

This led me to consider an alternative document structure:

{  
"localizedStr" : [  
{ "culture" : "en-us", "value" : "someValue"},  
{ "culture" : "es-es", "value" : "algunValor"},  
...  
]  
}

With this structure I know I can easily add more cultures to the system  
without having to change my mapping, but I'm not exactly sure how I can  
query for a value in a specific culture-locale.  
For example: if I were to query for localizedStr.culture : "en-us" AND  
localizedStr.value : "algunValor", this document would be returned,  
although that's not what I want.

Can someone provide some input on which of these makes most sense? If it's  
the second one, then how do I query values for a specific culture-locale?

Thanks.
