TOKEN_TYPE Oracle 8i interMedia question

Where can I find information about the meaning of column TOKEN_TYPE in table DR$<index_name>$I?

Till now I know that

0 = word

2 = tag

5 = tag_at_attribute

But what does mean "4"?

After indexing CLOB column with interMedia some words are not recognized as "WORDS". For example:

<AUTHOR name="Waldemar Lysiak"/>

I can find document by CONTAINS( 'Lysiak WITHIN AUTHOR_at_name' ) but not by CONTAINS( 'Waldemar Lysiak WITHIN AUTHOR_at_name' ) or CONTAINS( 'Waldemar WITHIN AUTHOR_at_name' ).

I checked, that token "WALDEMAR" has type "4" and "LYSIAK" has type "0". The same is with all such tokens with type "4" - I have big problems with searching them.

Does anyone have similar problems and knows the solution? Received on Fri Sep 08 2000 - 18:39:56 CEST
