Thank you for your answer. I'll try that asap and get back to u. Best

Is it correct that I would create the mapping like that: $ curl -XPUT "localhost:9200/my_index/my_type/_mapping" -d '{ "my_type":{ "properties":{ "message":{ "type":"string", "copy_to":"minhash_value" }, "minhash_value":{ "type":"minhash", "minhash_analyzer":"minhash_analyzer", "copy_bits_to" : "minhash_bits" },...
