pub struct ExpansionStats {

}Expand description
Summary statistics about how much a query was expanded.
Fields§
§original_term_count: usizeNumber of unique tokens in the original query.
expanded_term_count: usizeTotal number of terms in the expanded query (including originals).
expansion_ratio: f64expanded_term_count / original_term_count (or 0.0 if there are no
original terms).
sources: HashMap<String, usize>Number of terms contributed by each ExpansionSource variant.
