I have 2 indexes one of them is created using logstash and doesnt have any specific analyzer/normalizer applied to it and that index has more than 1M records but taking only 1GB memory space in each node. On the other hand I have another Index that I have created manually and applied 2 analyzers(Custom & Standard) to each and every text field. This index has 800k records and it is taking almost 5GB space in each node. Both the index has similar kind of data and fields are also same. So my query is why the second index is taking more space, is it only because of the analyzers or anything else? Any response will be appreciated.
