Wow, that's pretty big for the document count! - make sure that you only store fields you need to retrieve... if you only need to search on the fields, make them indexed-only. - unique terms take up more space... if you have date or time fields, try reducing the time resolution - if any stored fields are very large, perhaps try compression - application specific compression... for example, if you have a lot of URL values starting with the same thing change "http://"; to a single unique character. -Yonik
