Hello, I have a question regarding ngram configurations. Elastic search documentation says

> It usually makes sense to set min\_gram and max\_gram to the same value.

Perhaps, too much of difference between min and max grams will increase the index storage.

But there are many blogs which are using max\_gram as 8 or 20 to get higher accurate results.

I am confused between the two. Which should be the one to use?  
What are pros and cons of both?

Note: My use case deals with indexing of article. Article content is usually of size 150KB.

Thanks
