| A documental partitioning and clustering strategy that partitions an index into contiguous segments.
To partition an index in contiguous parts, you must provide an array
of cutpoints, which define each part. More precisely, given
cutpoints c0,c2,…,ck,
the global index will be partitioned into k local indices containing the documents
from c0 (included) to c1 (excluded), from
c1 (included) to c2 and so on. Note that
necessarily c0=0 and ck=N,
where N is the number of globally indexed documents.
The
ContiguousDocumentalStrategy.properties() method provides two properties, pointerfrom and pointerto,
that contain the first (included) and last (excluded) pointer in the local index.
