FW: Re: [ka-Map-users] Problem with Search in KAMAP with Postgis

[Melanie Ritzau]

What do I have to change in kaSearch.php to get a search-command like this:
 SELECT * FROM name where LOWER (name) = 'blahblah'  ??

Change

  $searchstring = "($szSearchfield ilike '%$psearch%')";

to

  $searchstring = "(LOWER($szSearchfield)  '$psearch')";
