Adding a sliding timeline index to the load definition file in the Load Definition File editor consists of the following steps:

Step 1

The first step is to select the Sliding Timeline task in the INDEXES task bar along the left side of the load definition file editor to activate the SLIDING TIMELINE INDEXES page if it isn't already activated. If the Sliding Timeline task is not enabled, be sure there is at least one date-time data field defined and has been mapped in the data parsing information of a data file section and/or the data parsing information of a document scanning section. A date-time data field is a numeric data field with either extract date, extract time or extract date-time special processing applied in the data parsing information. To learn how to add a data field see the Add Data Field topic. To learn how to add data parsing information to a data file section see the Add Data Parsing Information topic. To learn how to add data parsing information to a documents scanning section see the Add Data Parsing Information topic.

Step 2

The second step is to select the Add Index task in the SLIDING task bar along the right side of the SLIDING TIMELINE INDEXES page:

The Edit Sliding Timeline Index dialog box will appear:

Step 3

The third step is to specify the Index Name for the sliding timeline index being added:

The Index Name uniquely identifies each index.

Step 4

The fourth step is to enter the Resource ID for the timeline index being added:

The Resource ID is used internally to uniquely identify the index.

Step 5

The fifth step is to define the Index Rules for the timeline index being added:

The Sliding Timeline Index Rules allows you to specify the package and data field for which this index will be create over.

Use the Apply button of the Add Timeline Index Rule dialog box to add an index rule without closing the dialog box. Click the OK button to close the dialog box and add the index rule.

Step 6

The sixth step is to enter the Relative Base Time for the sliding timeline index being added:

The Relative Base Time must be a date-time literal or date-time expression that evaluates to a date and time, and should vary through time. If the expression does not vary through time, a regular primary timeline index should be used. The relative base time is re-evaluated each time the search engine load is being updated.

Step 7

The seventh step is to enter the Interval for the timeline index being added:

The Interval 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.

Step 8

The eighth step is to enter the Slot Count for the timeline index being added:

The Slot Count identifies the number of slots in the sliding timeline index. In the above example since our Relative Base Time is `tomorrow`, the Interval is 1 day going forward and the Slot Count is set at 14, the time span covered for this timeline index would be between whatever tomorrows date is until 14 days after tomorrows date.

Step 9

The ninth step is to enter the Weight for the sliding timeline index being added:

The Weighting value is the weight to be applied to results returned using this index. A value of either 0 or 1 gives the index equal weight with all other indexes.

Step 10

Since a sliding timeline index is must be a primary index the Primary Index check-box is disabled and checked.

The tenth step is to click the OK button to add the index to the sliding timeline index list:

The sliding timeline index is added to the list. Use the check-box to the left of each index to enable and disable the index. If the check-box is checked, the index is enabled and will be processed. If the check-box is unchecked, the index is disabled and will not be processed.
