I am using the query more\_like\_this to check the similarity between 2 texts. However the results are wrong (i put 2 identical documents and the similarity was not high) I think it can be related with the fields, because we are using fields with spaces and as i can see this is not really good. Could this be the reason? how should i improve the results?
