Were you actually trying to "...divides text at non-letters and
converts them to lower case"? Or were you trying to make it
non-case-sensitive, which would be KeywordTokenizer and
LowerCaseFilter?
Also, normally we do not use NGRam filter on both Index and Query.
That just makes things to match on common prefixes instead of matching
what you are searching for to a prefix of original word.
