We introduced prefix support in 8.4, so one may use:
=# select to_tsvector('Rumman went to iftekhar to solve it') @@ to_tsquery('ifte:*') as c;
c
---
t
(1 row)

I am using Postgresql 8.1 tsearch2.
I need to match a like operation in tsearch. Such as,
Sample data:
Document
......................
Rumman went to iftekhar to solve it.
select ...
from ...
where document like '%ifte%'
need to be written in tsearch. Here "ifte" is a name
But in tsearch when I am using to_tsvector, it gives as follows-
'iftekhar':4 'rumman':1 'solv':6 'went':2
postgres=# select to_tsvector('Rumman went to iftekhar to solve it') @@
to_tsquery('ifte') as c;
c

f
(1 row)
I am confused how to execute the above like operation in tsearch.
Any help please.
