Oracle 11G + Single sdata searching in Contains clause

Question

Hi,
Their is one domain index in my table on valueaddxml column, and another column is of queryid which is of varchar2(500)
Their are two records in the table.
one is :-
valueaddxml - > <?xml version="1.0" encoding="UTF-8"?><valueaddinfo><seqno>679</seqno></valueaddinfo>
queryid = 2
second is :-
valueaddxml - > <?xml version="1.0" encoding="UTF-8"?><valueaddinfo><seqno>888</seqno></valueaddinfo>
queryid = 1
the output of following query is :-
select queryid from v2_1244160000_1251936000 where contains(valueaddxml,'( haspath(/valueaddinfo\[seqno="679"\]))') > 0 and contains(valueaddxml,' (sdata(queryid = ''1'')) ') > 0 order by istimestamp desc
Output :- queryid - > 2
I dont know why oracle is showing such kind of behaviour with only sdata in contains clause.
Can i use contains(valueaddxml,' (sdata(queryid = ''1'')) ') > 0 clause ?
Is it compulsary to use other 'within' or any other clause with sdata ?
any help please ?

Answer 1

Let me make it more clear.
If i use this query (wrong output ):-
select queryid from v2_1244160000_1251936000 where contains(valueaddxml,'( haspath(/valueaddinfo\[seqno="679"\]))') > 0 and contains(valueaddxml,' (sdata(queryid = ''1'')) ') > 0 order by istimestamp desc
Output is :- queryid = 2
If i use query ( Correct output ) :-
select queryid from v2_1244160000_1251936000 where contains(valueaddxml,'( haspath(/valueaddinfo\[seqno="679"\])) and (sdata(queryid = ''1'')) ') > 0 order by istimestamp desc
Ouput is :- no data avaliable.
Why can not i use the first one instead of second ?
