Struct EdgeNGramTokenizer

Source

pub struct EdgeNGramTokenizer {
    pub min_gram: usize,
    pub max_gram: usize,
    pub token_chars: Vec<TokenChar>,
}

Expand description

Produces edge n-grams (prefix n-grams) from the input text.

Like NGramTokenizer but n-grams are anchored to the beginning of each word. Used for autocomplete / search-as-you-type.

Matches ES edge_ngram tokenizer.

See [[analyzers#Tokenizer]].
