BOOST

The BOOST scoring function tailors the importance of a specific search expression within a query, offering a boost to its relevance. It defaults to a value of 1.0.

Syntax​

BOOST(expr, boost)

expr (expression): A valid search expression. boost (number): Numeric boost value.

Example​

The following example searches for documents that contain either "foo" or "bar" and sorts the results based on their relevance using the BM25 scoring function:

FOR doc IN viewName
  SEARCH ANALYZER(BOOST(doc.text == "foo", 2.5) OR doc.text == "bar", "text_en")
  LET score = BM25(doc)
  SORT score DESC
  RETURN { text: doc.text, score }
