The big job is populating the index columns. I think you can only put
the full text index column in the same table as the referenced
columns. In other words, you will end up with 3 tables, each with a
ftidx column. I hope your docs show how to create and populate the
indexes and to create triggers to keep them up to date.
To search across 3 tables I would do something like
select ...
from t1 join t2 on ... join t3 on...
where t1.idxfti @@ 'test'::tsquery
or t2.idxfti @@ 'test'::tsquery
or t2.idxfti @@ 'test'::tsquery
If there is an easier better way, I don't know it!
I can email you the very good intro and readme files directly if you need them.
