I am using shards to provide access to several underlying indexes which have drastically different schema. Each different shard has its own dedicated search application built around it. However I also want to implement a global search that performs a more limited but general purpose search across all shards. I find I am doing lots of copyfields to get a set of fields that can be used for the general purpose search, I feel sure that this is redundant and that an aliasfields feature would be very useful. For example one index has a "title" field another has a "subject" field a third has a "placename" field. My general purpose or global search treats these as as title. An aliasfields feature would be more efficient and cleaner than using copyfields. Fergus. > >2009/6/5 Noble Paul ??????
