5.14 Passing Extractor-Specific Parameters in CREATE INDEX and ALTER INDEX

The CREATE INDEX and ALTER INDEX statements allow the passing of parameters needed by extractors.

These parameters are passed on to the extractor using the params parameter of the extractRdf and batchExtractRdf methods. The following two examples show their use:

CREATE INDEX ArticleIndex on Newsfeed (article)
  INDEXTYPE IS mdsys.SemContext PARAMETERS ('SEM_EXTR=(NE_ONLY)');

ALTER INDEX ArticleIndex REBUILD 
  PARAMETERS ('-add_policy MY_POLICY=(NE_ONLY)');
