Thanks for your prompt response.  I will try to make my questions not so vague anymore.  This the version of postgres and red hat I'm using:
service0=# select version();
                                                 version
---------------------------------------------------------------------------------------------------------
 PostgreSQL 7.2.4 on i686-pc-linux-gnu, compiled by GCC gcc (GCC) 3.2 20020903 (Red Hat Linux 8.0 3.2-7)
(1 row)
I am using OpenACS version 4.6.3.
This is the result when I type in the different queries you asked me:
service0=# select count(*) from search_observer_queue;
 count
-------
     0
(1 row)
service0=# select * from search_observer_queue;
 object_id | event_date | event
-----------+------------+-------
(0 rows)
service0=# select count(*) from txt;
 count
-------
     0
(1 row)
From I am seeing and what I read from different forums answers and documentations is that I have not made any object searchable.  How do I go about that?  What is an object anyways?  I know I am asking so many basics questions, please bear with me.  Once again, thank you for your help.

PS:  I also get this error on my log file.  It seems like there is an attempt for a email deliver, but the attempt is failing.
