Indexes are built on particular text or metadata sources. The search space can
be further controlled by partitioning the index, either by language or by a
predetermined filter. This section describes how to do this. Under "Design
Sections", click "Partition Indexes".
The "Partition Indexes" view has three tabs; "Define Filters", "Assign
Partitions" and "Assign Languages". To learn more about partitions read about
subcollections and subindexes in Chapter 2 of the Greenstone Developer's Guide.
