Problem with Special character in Oracle Text Manager

[ganesh]

Dear folks,

I am using Oracle Text Manager for full text search and synonym
search.

To escape a special character }, }} is used. It is working fine for
Fuzzy and Phonetic search but not for Synonym search.

My query is
SELECT NAME,SCORE(1) FROM DRUG
WHERE CONTAINS(NAME,'SYN(A}}B,SYNONYM_LIST)',1) > 0;

If i execute the above query, an Oracle parsing error occured. I am
doing the above the above test to validate the search query given by
the user.

The term A}B is defined in the Thesaurus called synonym_list as
A}B
UF FEVER
UF COLD

Executing the following query also returns same error, since Fever is
a synonym of A}B.
SELECT NAME,SCORE(1) FROM DRUG
WHERE CONTAINS(NAME,'SYN(Fever,SYNONYM_LIST)',1) > 0;

How to avoid this situitation.

Any help will be appreciated.
