* Do you use EdgeNGramFilter in index analyzer only? Or you also use it on query side as well?
* What if you create additional field first_letter (string) and put first character/characters (multivalued?) there in your external processing code. And then during search you can filter all documents that start with letter "a" using fq=a filter query. Would that solve your performance problems? * It makes sense to specify what are you trying to achieve and probably more people can help you with that.
