Struct Bm25TextConfig 

pub struct Bm25TextConfig {
    pub params: Bm25Params,
    pub tokenizer: Tokenizer,
    pub language: Language,
    pub lowercase: bool,
    pub ascii_folding: bool,
    pub stopwords: Option<Stopwords>,
    pub stemmer: Option<Stemmer>,
    pub min_token_len: Option<usize>,
    pub max_token_len: Option<usize>,
}

Full BM25 text-processing configuration — mirrors Qdrant’s Bm25Config.

Construct via Bm25TextConfig::resolve (flat stringly options, the single choke point every config surface calls) or struct-literal with ..Default::default(). Numeric parameters validate through Bm25Params; names parse through Language/Tokenizer/Stemmer.

Fields

params: Bm25Params

Validated k1/b/avg_len.

tokenizer: Tokenizer

Tokenizer (default Tokenizer::Word).

language: Language

Language for default stopwords/stemmer (default English, like Qdrant).

lowercase: bool

Lowercase before matching (default true, like Qdrant).

ascii_folding: bool

Lucene ASCII folding before lowercasing (default false, like Qdrant).

stopwords: Option<Stopwords>

Stopword override (None = language default).

stemmer: Option<Stemmer>

Stemmer override (None = language default).

min_token_len: Option<usize>

Drop tokens shorter than this (chars, always enforced, like Qdrant).

max_token_len: Option<usize>

Drop tokens longer than this (chars; on the document path, like Qdrant — the prefix query path truncates instead).

Implementations

impl Bm25TextConfig

pub fn resolve( k1: Option<f64>, b: Option<f64>, avg_len: Option<f64>, language: Option<&str>, tokenizer: Option<&str>, lowercase: Option<bool>, ascii_folding: Option<bool>, stopwords: Option<Vec<String>>, stemmer: Option<&str>, min_token_len: Option<usize>, max_token_len: Option<usize>, stopwords_languages: Option<Vec<String>>, ) -> Result<Self, QqlError>

Resolve flat options into a validated config. None keeps the corresponding default; invalid names or numbers fail closed with QQL-VALIDATION-CONFIG.

• stopwords: None = language default; Some(list) replaces it with exactly list (empty disables filtering). Use stopwords_languages to merge additional language lists instead.
• stopwords_languages: additional language lists merged with stopwords (Qdrant Set.languages). An explicit selection replaces the default, so include the processing language to keep its words. Invalid names fail closed.
• stemmer: None = language default; Some("none") disables; Some("<language>") overrides.
• tokenizer: "multilingual" parses here but fails at embed time (see Tokenizer::Multilingual).

pub fn with_text_options( &self, language: Option<&str>, tokenizer: Option<&str>, lowercase: Option<bool>, ascii_folding: Option<bool>, stopwords: Option<Vec<String>>, stemmer: Option<&str>, min_token_len: Option<usize>, max_token_len: Option<usize>, stopwords_languages: Option<Vec<String>>, ) -> Result<Self, QqlError>

Update text knobs over the current config: None (or empty names) keeps self’s value, explicit values replace it. Unlike Bm25TextConfig::resolve, where None means “Qdrant default”, this is the incremental-update path (WASM setBm25Text, REPL-style tuning): previously configured values survive untouched knobs. Names validate exactly like Bm25TextConfig::resolve. There is no reset-to-default signal: to restore defaults, resolve a fresh Bm25TextConfig::default instead of updating.

pub fn pipeline(&self) -> Bm25Pipeline

Compile into an executable pipeline. Infallible: names already validated at parse/resolve time; remaining choices are total.
