I have a need to index on a CLOB column. Initial attempts to index will result in ORA-02373.
In research, I was able to find an that a LOB column could be moved to another tablespace then indexed.

So I plan to use these statements (below), to create a text index on CLOB column STATEMENT_TEXT.
Questions: What storage should be used for the CLOB column?
What index type is needed to create a text index on the CLOB column?

ALTER TABLE ANY_STATEMENT MOVE
TABLESPACE INFOWH2 STORAGE(INITIAL 4096K)
LOB (STATEMENT_TEXT) STORE lobsegment
(TABLESPACE INFOWH2 STORAGE (INITIAL 4096K));

Then:
CREATE INDEX IDXANYSTMTTEXTBINARY
ON LOB(STATEMENT_TEXT)
INDEXTYPE IS CTXSYS.CONTEXT;


Here is the table in part:
CREATE TABLE ANY_STATEMENT
(
ANY_STATEMENT_ID CHAR(18 BYTE) NOT NULL,
CODE VARCHAR2(4 BYTE),
STATEMENT_TYPE_ID_FK CHAR(18 BYTE) NOT NULL,
UPDATED_BY VARCHAR2(50 BYTE) DEFAULT USER,
LAST_DATE_UPDATED DATE DEFAULT SYSDATE,
DESTINATION_ID_FK CHAR(18 BYTE),
LANGUAGE_ID_FK CHAR(18 BYTE) NOT NULL,
SUPERCEDED_DATE DATE,
FORMULA_REFERENCE NUMBER,
FORMULA_SERIAL VARCHAR2(15 BYTE),
CREATED_BY_ID_FK CHAR(18 BYTE) DEFAULT USER NOT NULL,
DATE_CREATED DATE DEFAULT SYSDATE NOT NULL,
ON_HOLD CHAR(1 BYTE),
TEMP_REFERENCE_NUMBER NUMBER,
APPLICATION_NOTES VARCHAR2(2048 BYTE),
HOLD_REASON VARCHAR2(1024 BYTE),
STATEMENT_TEXT CLOB,
REASON CLOB
)
