While setting up a Google Mini search for a site recently, I kept getting an error message like this:
/export/hda3/4.3.105.M.6/local/conf/frontends/default_Frontend/domain_filter (No such file or directory)
When trying to use the XML API to get the results back. I tried various things and eventually contacted the host to make sure their setup wasn’t blocking anything. Eventually I realised the Collection and Front End settings are case sensitive and I had mine in all-lowercase as I’d been told, whereas the Mini was actually set up with capitalised first letter. Once I’d matched what they were in the Mini, the error stopped. You can also get the same error with the Google Search Appliance.
Simple, but so easy to get caught out by it!
