An error occured while searching.
Searching after "tsearch2full"
An error occured while searching.
This error can be generalized to the reg-ex [::alpha::]+[::digit::]+
Examples:
A1
A2 etc...
Why is it so? =)
Seems to_tsvecto() returns NULL for tsearch2 or for, as you say,
anything that ends in a digit.
Oleg, can you comment on why this is happening? What can we do to fix
that?
Most probably, token type 'word' just doesn't indexed. If you
didnt' correct this from pgweb configuration:
-- we won't index/search some tokens
update pg_ts_cfgmap set dict_name = NULL
where tok_alias in ('email', 'url', 'sfloat', 'uri', 'float','word')
and ts_name = 'pg';
