I have a workaround to the error/result, but am wondering what the result of ts_rank of '1e-020' represents?

Here is the original:

select
ts_rank(to_tsvector('a_a_do_ug_read_retreqmon_ptam'),to_tsquery('a_a_do_ug_read_retrmso.com_ptam'))

I get essentialy the same result with pg 9.1.1

----------------
 9.99999968e-21
(1 row)

I am also on "PostgreSQL 9.1.1"

Thanks for posting the   9.99999968e-21, I did not realize it was using notation to represent a number, I thought it was an error code.  That is good news - thank you for taking the time ans showing me your result - that solves it.
