	TODO: encoding somehow wrong, but hex-unicode seems to be a browser problem only; wt=xml looks strange, since json is output format; 
	can enforce wt=json, but than portal facet search is no longer working
	check whether to use one SOLR core for portal and API or better two separate cores -> need specification what is required from 
	third parties such as EOL, GBIF, INSDC, and EDIT
	If we can use same SOLR core for both would it be easier to use the web service for portal too?
	
	Currently working parameters: unitID, sampleType, name, country, isocountry
