I am learning Oracle Text and created the above routine to check whether Russia/Russian appears in the OracleTextDeveloper.txt file (text version of the standard Oracle documentation - B28303-03). Am I missing something?
Some more information: -
DBMS_METADATA.GET_DDL('INDEX','IDCTXR_BOOKS_CAT')
CREATE INDEX "READER"."IDCTXR_BOOKS_CAT" ON "READER"."BOO
KS_CAT" ("QRY")
INDEXTYPE IS "CTXSYS"."CTXRULE"
SQL> select token_text, token_type from dr$idctxr_books_cat$i;
TOKEN_TEXT          TOKEN_TYPE
ORACLE                    0
RDBMS                         0
RUSSIA                         0
