Database Software

I have a table called auction :

Create table auction(item_id varchar2(10), title varchar2(100));

Create table auction(item_id varchar2(10), title varchar2(100));

I create created a context index on the title column :

create index AUCTION_TITLE_CONTEX on auction(title) indextype is ctxsys.context parameters ('DATASTORE CTXSYS.DEFAULT_DATASTORE');

create index AUCTION_TITLE_CONTEX on auction(title) indextype is ctxsys.context parameters ('DATASTORE CTXSYS.DEFAULT_DATASTORE');

I insert inserted some data in the table :

insert into auction values ('1','wilkin');

select score(1), title FROM AUCTION where contains(title,'fuzzy('wilkin',,,weight)',1) >0 order by score(1) desc;

insert into auction values ('1','wilkin');  select score(1), title FROM AUCTION where contains(title,'fuzzy('wilkin',,,weight)',1) >0 order by score(1) desc;

the The result for the score(1) is 48.

You can see that 'wilkin' is an exact match to 'wilkin' .

Why is the score is not 100?

what What can i I do in my index for all exact match matches to give 100 as score?

Thank you?
