The interval property of the sliding timeline index is the time span mapped by each slot. The time span must be a date-time literal or date-time expression that evaluates to a duration value. The time span is evaluated at the time the load is first initialized by LoadInit, and is never altered.




Relative Base Time



`-1 day`

Slot Count


The above example uses a relative base time of `today`, which is reevaluated each time the search engine load is updated. The index will map a total of seven days, with one days worth of items mapped to an individual slot. As time moves forward, the limits of the timeline are automatically adjusted. Items falling outside the new timeline are removed from the data-store and associated indexes.
