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)');
