You can get into trouble if it comes from another record in the same file or another file entirely, although it can be done if the other file contains "stable" data - a word index for example, where you have a secondary file that contains words that are not included in the index, and the list is updated with all the dependent indices as part of a maintenance routine. -----Original Message----- From: u2-users-boun...@listserver.u2ug.org [mailto:u2-users-boun...@listserver.u2ug.org] On Behalf Of Israel, John R. Sent: Tuesday, March 06, 2012 1:41 PM To: 'U2 Users List' Subject: [U2] Indexing I-Desc I have a select that is taking too long. Many of the fields are I-Descs. Some are extracting a piece of info from the file, some are translates to other files, and some are running subroutines. I understand that danger of indexing a translate or subroutine (if the source data changes, the index is not updated). However, I am toying with the idea of building a new I-desc that in some way combines the data in the core file itself. For example, if I need F11 & F20[4,1] and F40, make an I-desc that combines these and then index that I-desc. Just as a sanity check, does this sound like a reasonable thing to do so that I can at least grab a subset of the data I need prior to actually plowing through the translates and subroutines?
