8.6: Cross-Collection Search

Greenstone can search across several different collections as though they were one. This is done by specifying a list of other collections to be searched along with the current one. Under the "Format" tab, click "Cross-Collection Search".

The Cross-Collection Search panel shows a checklist of available collections. The current collection is ticked and cannot be de-selected. To add another collection to be searched in parallel, click it in the list (click again to remove it). If only one collection is selected, there is no cross-collection searching.

If the individual collections do not have the same indexes (including sub-collection partitions and language partitions) as each other, cross-collection searching will not work properly. The user will only be able to search using indexes common to all collections.
