Create Fulltext Index on DATE Column - not supported?

Hi, all,

How can I create a fulltext index on DATE column?

I created the new column table ZHA400_SFLIGHT with field FLDATE, which was created as (excerp from CREATE statement):

..."FLDATE" DATE DEFAULT '' NOT NULL...

I populated the table with some test values - everything seemed OK (the dates were correctly inserted too).

Then I tried:

CREATE FULLTEXT INDEX zfl_date ON zha400_sflight(fldate) FUZZY SEARCH INDEX ON;

and I have got the message:

cannot create fulltext index: not supported type DAYDATE of column FLDATE.

I am obviously doing something wrong, but can't figure out what.

Thanks in advance for your help!

KR,

Igor
