I need to ask a question of someone who understands Oracle Text indexes. So if you know Oracle Text, please read on.

I was told that if I had a query such as the following:

SELECT falls_name
FROM waterfalls
WHERE INSTR(UPPER(falls_directions),

'MACKINAC BRIDGE') <> 0;

where falls_directions is a CLOB, that I can define a case-insensitive index using Oracle Text and then use CONTAINS to execute the query more efficiently:

SELECT falls_name
FROM waterfalls
WHERE
CONTAINS(falls_directions,'mackinac bridge') > 0;

Is this correct? Is there such a thing as a case-insensitive index in Oracle Text? I did take a quick look at the Oracle Text manual, but this capability didn't leap out at me. Is "case-insensitive" the term Oracle Text uses? In any case, I need to verify whether what I've been told is correct.
