All Implemented Interfaces:

TokenizerFactory

public class TrieTokenizerFactory
extends BaseTokenizerFactory

Tokenizer for trie fields. It uses NumericTokenStream to create multiple trie encoded string per number. Each string created by this tokenizer for a given number differs from the previous by the given precisionStep. For query time token streams that only contain the highest precision term, use 32/64 as precisionStep.

Refer to NumericRangeQuery for more details.
