Even after creating a full text index by
CREATE FULLTEXT INDEX FT_TESTTABLE_TEXT1 ON TESTTABLE(TEXT1) TEXT ANALYSIS ON CONFIGURATION 'LINGANALYSIS_FULL' LANGUAGE COLUMN "LANGU"
no tokenized data will be set to $FE_TESTTABLE_TEXT1.
Though some results are returned by replacing 'LINGANALYSIS_FULL' with 'indexConfigNER.xml', but I don't think it's the same as LINGANALYSIS_FULL.
Also some answers mentioned that delivery unit (HANA_TA_CONFIG.tgz) should be imported, but how can it be done on HCP, especially with a free account (with limited system access)???
