I'm working on a model where i will have the input data in _AVRO_ format and index the data into _ES_. Before indexing I would like to add catagories to the data i.e _Auto_-\* Classification\*. eg: the data contains books. Each book will have a field topics or text. Now before indexing i would like to assign catagories to it. Say a particular book is for hadoop, servlets etc.there may be n number of catagories assigned. Any suggestions as to how i can proceed. Is there any plugin available for the same? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
