The ALTER INDEX and CREATE INDEX statements support incrementally creating a global CONTEXT index.
For creating a global index, CREATE INDEX supports the NOPOPULATE keyword of the REBUILD clause. Using the NOPOPULATE keyword in the REPLACE parameter, you can create indexes incrementally. This is valuable for creating text indexes in large installations that cannot afford to have the indexing process running continuously.
For creating a local index partition, ALTER INDEX ... REBUILD partition ... parameters ('REPLACE ...') parameter string is modified to support the NOPOPULATE keyword.
For creating a partition on a local index, CREATE INDEX ... LOCAL ... (partition ... parameters ('NOPOPULATE')) is supported. The partition-level POPULATE or NOPOPULATE keywords override any POPULATE or NOPOPULATE specified at the index level.
