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?, $options as map:map?) as map:map {
op:from-search($query, ('confidence', 'fitness', 'fragmentId', 'quality', 'score'), $qualifier, $options)
=> op:order-by(op:desc('score'))
=> op:join-doc-and-uri('doc', op:fragment-id-col('fragmentId'))
};
Please note that if you have other Optic functions following op:from-search-docs, it may change
the ordering of the results.
