Hi all, I am trying to wrap my head around indexing a field with ngrams of multiple lengths (e.g. 3 to 8). What I am trying understand is how the quality of matches is correlated with the number of ngrams. This discussion had quite of bit of useful info: [https://groups.google.com/d/topic/elasticsearch/QXYvb27Pvl8/discussion](https://groups.google.com/d/topic/elasticsearch/QXYvb27Pvl8/discussion) but it doesn't really help with figureing out _what_ the range should be. Ideally I'd like a calculator that shows the relationship between ngram parameters, index size, and expected query time. But of course I understand that without a full description of the source data and use cases this is just about impossible. Any pointers would be helpful. Thanks!
