Search particular column using WITHIN operator in rewrite query template in Oracle Text - oracle-sqldeveloper

Question

I have one query regarding usage of query template in oracle text.I am using below query but not able to figure out how to restrict it to particular column search , I tried using WITHIN operator but it is not considering it. Any help will be appreciated. Thanks.<query><textquery lang="ENGLISH" grammar="CONTEXT" >' || p_search ||'<progression><seq><rewrite>transform((TOKENS, "{", "}" within contact_name, " ")) </rewrite></seq><seq><rewrite>transform((TOKENS , "{", "}" within contact_name, " NEAR ")) </rewrite></seq><seq><rewrite>transform((TOKENS , "{", "}" within contact_name, "OR")) </rewrite></seq><seq><rewrite>transform((TOKENS , "fuzzy(", ", 50)" within contact_name, " ")) </rewrite></seq></progression></textquery><score datatype="FLOAT" algorithm="COUNT"/></query>
I am trying to use the above query template in Contains operator to fetch the results but I see it is scanning whole document instead of single node.(contact_name in my case) .
I have stored the data in JSON format in my master table.
Thanks.
select * from (select /*+ FIRST_ROWS(20) */ ccc.name
,ccc.value
,ccc.job_title
,ccc.customer_id
,ccc.contact_id
,score(0) score
,score(0) score0
from customer_contacts ccc
right join customers ccu
on ccu.customer_id = ccc.customer_id
where (contains(ccu.search_col_js, '<query>
<textquery lang="ENGLISH" grammar="CONTEXT" >' || :p_search ||'
<progression>
<seq><rewrite>transform((TOKENS, "{", "}" within contact_name, " ")) </rewrite></seq>
<seq><rewrite>transform((TOKENS , "{", "}" within contact_name, " NEAR ")) </rewrite></seq>
<seq><rewrite>transform((TOKENS , "{", "}" within contact_name, "OR")) </rewrite></seq>
<seq><rewrite>transform((TOKENS , "fuzzy(", ", 50)" within contact_name, " ")) </rewrite></seq>
</progression>
</textquery>
<score datatype="FLOAT" algorithm="COUNT"/>
</query>' ,0) > 1)
and :P1_SEARCH_CUSTOMER is not null
order by score desc
);
