op:from-search-docs(
   $query as cts:query,
   [$qualifier as xs:string?],
   [$options as map:map]
) as map:map

Summary

This function matches and returns the uri, content, and score for documents.

Parameters
$query Qualifies and establishes the scores for a set of documents. The query can be a cts:query or a string as a shortcut for a cts:word-query.
$qualifier Specifies a name for qualifying the column names.
$options Similar to the options of cts:search, supplies the 'scoreMethod' key with a value of 'logtfidf', 'logtf', 'simple', 'zero', 'random', or 'bm25' to specify the method for assigning a score to matched documents or supplies the 'qualityWeight' key with a numeric value to specify a multiplier for the quality contribution to the score. Specify a value between 0 (exclusive) and 1 (inclusive) for bm25LengthWeight if 'bm25' scoring method is used.

Usage Notes

The op:from-search-docs function is a convenience for executing a op:from-search equivalent to: 

declare function local:from-search-docs($query as cts:query, $qualifier as xs:string?) as map:map {
   op:from-search($query, (), $qualifier)
     => op:join-doc-uri('uri', op:fragment-id-col('fragmentId'))
     => op:order-by(op:desc('score'))
     => op:join-doc('doc', op:fragment-id-col('fragmentId'))
     => op:order-by(op:desc('score'))
};
