Refreshing view indexes
A view index is an internal filing system that builds a list of documents that belong in a view. When users add or change documents, the view index must be refreshed to show them which documents are new or changed. Refreshing a view index can occur manually when users press F9, as part of a condition built into the view design, or as part of the Updall (Update ALL) server process set up by the server administrator.

You can either create a full-text index for a database or allow users create a full-text index. If you want to maintain control over creating an index, choose the option "Restrict initial index build to designer or manager."

Refresh time options

To determine when to refresh an individual view, select a "Refresh index" option from the Advanced tab of the View Properties box.


Refresh display options

The On Refresh options on the Options tab of the View Properties box determine how users see the changes in a view. The choices are:


Discard index options

To delete indexes automatically for a particular view and save disk space, specify a "Discard index" option from the Advanced tab of the View Properties box. (Note that when users open a view whose index has been discarded, they may have to wait for IBMR LotusR Domino(TM) to recreate a view index.) These settings override the NOTES.INI setting "Default_Index_Lifetime_Days," which the server administrator sets and which, by default, deletes view indexes after 45 days.


When the view index is deleted

The Updall (Update All) server task, which runs by default on each server at 2 AM, deletes the view index. Domino deletes the index the first time Updall runs after the index becomes eligible for deletion. For example, if you select "After each use" and the view is used at 10 AM Tuesday, the index is not actually discarded until 2 AM Wednesday.

If you choose to delete the index after one day, Domino waits until the index is at least one day (24 hours) old before deleting it. If the view is used at 10 AM Tuesday, it is only 16 hours old at 2 AM Wednesday when Updall runs, so it is not deleted until the next time Updall runs at 2 AM Thursday.
