Hi,  
Can i ask what the recommendations are regarding aliases and time based indices? I ask because we encourage constrained searching with our users apps. if we use an alias for these indices (wildcarding) then all searches using the alias will be global.

Regards,  
David

You can have an alias named weekly which goes only to the last 7 days indices.  
And switch the alias every day by removing the older day and adding the new one.

Is that what you are looking for?
