EdgeNGramFilterFactory没有像这样的任何参数

它有两个参数

minGramSize: (integer, default 1) The minimum gram size.
maxGramSize: (integer, default 1) The maximum gram size.

但你可以在这里试试tokenizer

有选项

minGramSize: (integer, default is 1) The minimum n-gram size, must be > 0.
maxGramSize: (integer, default is 1) The maximum n-gram size, must be >= minGramSize.
side: ("front" or "back", default is "front") Whether to compute the n-grams from the beginning (front) of the text or from the end (back).
