HI, PPL! How am I able to sort query results by relevance? I use contrib/tsearch to search using fill text index! -- WBR, sector119 msg09000/pgp0.pgp Description: PGP signature
[SQL] Sort by relevance
Hello,I am trying to use a perl script to break an input string
into keywords andpull out all the records that match any of them:my
(@chips)= split(' ', $f_name);foreach my $chip (@chips)
{ next if ($stoppers=~/ $chip / || length($chip) <
3); if ($query) {$query .= " OR name ~* '.*$chip.*'
";} else {$query = "SELECT * FROM info WHERE name ~*
'.*$chip.*' ";}}this works fine for pulling the records but I would
like to sort them by howmany of the "chips" matched.On a set
like:name-Bill SmithTed SmithTed
Brownan input of : Ted Smithwould give me a query string
of: SELECT * FROM info WHERE name
~* '.*Ted.*' or name~*'.*Smith.*'which returns all records - which is
what I want - but I would like to haveTed Smith in the first row followed by
the other records grouped by name andsorted on another column (city or
state in the real table)Thanks for your help,Chad
