CONTAINS Operator using ESCAPE character

Question

I must to do a SELECT sentence with a column with a domain index using CONTAINS. I need to look for a text that includes "%", but I want that the query recognizes it like literal and not like joker. I proved using the escape characters "\" and "{}", but I do not know if it does consider to the character "%" or if it uses it like comodín. The query is the next (if i need to find "6%"):
SELECT v.campo1, v.campo2
FROM promo_busqueda_leyes.s_version_xml v
WHERE contains (v.campo_xml, '(6\%)', 1)>0
or
SELECT v.campo1, v.campo2
FROM promo_busqueda_leyes.s_version_xml v
WHERE contains (v.campo_xml, '(6{%})', 1)>0
what am I making wrong?

Answer 1

if i understood correctly, try like this....
use INSTR instead of CONTAINS ie
WHERE contains (v.campo_xml, '(6\%)', 1)>0WHERE INSTR (v.campo_xml, '(6\%)', 1)>0
