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

I am not sure if I really have your latest build, because file-datum of kaSearch.php is 16.06.07.
I downloaded from here:http://ka-map.ominiverdi.org/CVSimg/ka-map-cvs-image.tar.gz
Nothing has changed - PostGIS-Search works but not Shapefile-Search. If I use again the old kaSearch.php the Shapefile-Search works fine.
For those who are interested in performance:
A (ka-)search in a Shapefile (500MB) with 2.5 Million places takes about 9-12 seconds.
The shapefile is not indexed. shptree was not possible with a file of this size and i guess a spatial index won't help for a name-search. I am not sure if Mapserver can interpret other indeces as qix (e.g. ArcGIS-indeces ??)
Same Shapefile converted to PostGIS-database takes 4-6 seconds (still to much) for KaMap-search. (on LINUX with ATHLON 64 X2 4200)
A search using "ilike" is very time consuming. What do I have to change in kaSearch.php to get a search-command like this:
SELECT * FROM name where LOWER (name) = 'blahblah' ??
So if I search for 'paris' I want to find only "Paris" and not "Villeparisis"
This is muuch faster cause PostGIS can also use an index.
Thanks,
Mel
