Change default mapping of string to “not analyzed” in Elasticsearch

阅读更多关于 Change default mapping of string to “not analyzed” in Elasticsearch

But whenever I input a string it is always taken to be analyzed , as a result an entry like hello I am Sinha is split into hello , I , am , Sinha . Is there anyway I could change the default/dynamic mapping of elasticsearch so that all strings, irrespective of index, irrespective of type are taken to be not analyzed ? Or is there a way of setting it in the .conf file? Say my conf file looks like input { file { path => "/home/sagnik/work/logstash-1.4.2/bin/promosms_dec15.csv" type
