Re: ts_rank error/result of '1e-020'

[Henry Drexler <alonup8tb@xxxxxxxxx>]

it sent before I finished, here is the rest:

I have fixed this by doing the following:

select

ts_rank(to_tsvector(replace('a_a_do_ug_read_retreqmon_ptam','_',' ')),plainto_tsquery(replace('a_a_do_ug_read_retrmso.com_ptam','_',' ')))

so I have found a solution, just wondering what the earlier error means/what causes it.  I could not find any references to that error in documentation or in help searches.
