Struct AsciiFoldingFilter

Source

pub struct AsciiFoldingFilter {
    pub preserve_original: bool,
}

Expand description

Converts Unicode characters to their ASCII equivalents.

Follows Lucene’s ASCIIFoldingFilter — a lookup table covering Latin Extended, IPA Extensions, Presentation Forms, and more. Characters below U+0080 pass through unchanged (fast path).

Matches ES asciifolding token filter.

See [[analyzers#Token Filters]].
