end

51. def search
@searchType = params[:search_type]
@searchCriteria = params[:search_criteria].upcase
service = ArcServer::MapServer.new('http://sampleserver1.arcgisonline
@jsonString = service.query(1,
{:where=>"#{@searchType} like '%#{@searchCriteria}%'",
:outFields=>'TLID, OWNER1,OWNER2,OWNER3,SITEADDR'
})
@json = JSON.parse(@jsonString)
@results = @json['features']
if @results.nil? || @results.length == 0
flash[:notice] = 'No results found for search ' + @searchCriteria
+ ' Please try another search.'
end
