: MobileInfo. Now obviously, I need to index MobileInfo to support faceted : browsing. How should I index SellingItem? The simplest way probably is to : combile mobile phone specs in MobileInfo and and fields in SellingItem, and : then index all of them. In this case, if I have 1000 SellingItems : referencing a particular MobileInfo, I have to repeat the fields in : MobileInfo a thousand times.
it depends on what you want ... hwat is the primary *thing* you want to return from a search? .. is it a MobileInfo instance, from which people can look at the list of mapped SellingItem isntances, or is it a SellingItem instance, from which people can look at the relevent MobileInfo? ... whatever that case *that* should be your document -- how many extra fields you have hanging off of those documents is largely irrelevant (particularly if those fields are Stored by not indexed, which is what it seems like you would do if you made MobileInfo the documents, and just wanted to be able to return the list of SellingItem instances for each one) Personally: I'd probably use two indexes: let people browse/search "models" using an index with MobileInfo based documents, and once they pick a model they like, search for it's identifier in a seperate "SellingItems" based index. -Hoss
