i have the a fieldtype that uses ngramfilter whle indexing. is there a
setting that can force the ngramfilter to index smaller words then the
minGramSize? Mine is set to 3 and the search wont find word that are only
1 or 2 chars long. i would like to not set minGramSize=1 because the
results would be to diverse.
fieldtype:
