"Exact match" in Object Search does not work properly. (4334712)

"Exact match" in Object Search does not work properly.

Object search does not find some objects when selecting "Exact match" option.
Please find below the steps to reproduce the problem
1.Run the script below:
CREATE TABLE PROVINCIA (QQ VARCHAR2 (1 BYTE))
TABLESPACE USERS
/
CREATE TABLE PROVINCIAS (QQ VARCHAR2 (1 BYTE))
TABLESPACE USERS
/
CREATE OR REPLACE PACKAGE test_object_search_pck
AS
   PROCEDURE test_object_search_proc;
END test_object_search_pck;
/
CREATE OR REPLACE PACKAGE BODY test_object_search_pck
AS
   PROCEDURE test_object_search_proc
   IS
      P_count   NUMBER := 0;
   BEGIN
      SELECT COUNT (*)
        INTO p_count
        FROM PROVINCIA A;
   END test_object_search_proc;
END test_object_search_pck;
/
2.go to Find | Object search and look for PROVINCIA
select "Exact match"(make sure you have package body checked in the options )
Toad should find the package test_object_search_pck as the work PROVINCIA is in there but toad does not find it
