Struct elasticsearch_dsl::search::queries::params::TieBreaker [−][src]
pub struct TieBreaker(_);Expand description
Floating point number between 0 and 1.0 used to increase the
relevance scores
of documents matching multiple query clauses. Defaults to 0.0.
You can use the tie_breaker value to assign higher relevance scores to
documents that contain the same term in multiple fields than documents that
contain this term in only the best of those multiple fields, without
confusing this with the better case of two different terms in the multiple
fields.
If a document matches multiple clauses, the dis_max query calculates
the relevance score for the document as follows:
- Take the relevance score from a matching clause with the highest score.
- Multiply the score from any other matching clauses by the tie_breaker value.
- Add the highest score to the multiplied scores.
If the tie_breaker value is greater than 0.0, all matching clauses
count, but the clause with the highest score counts most.
