op.fromSearchDocs

op.fromSearchDocs(
   query as cts.query,
   [qualifier as String?],
   [options as objectLiteral]
) as ModifyPlan

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.wordQuery.
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', or 'simple' 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. 'logtfidf' is the default score method and the results are ordered by score by default.

Usage Notes

The op.fromSearchDocs function is a convenience for executing a op.fromSearch equivalent to: 

function fromSearchDocs(query, qualifier) {
   return op.fromSearch(query, null, qualifier)
            .joinDocUri('uri', op.fragmentIdCol('fragmentId'))
            .orderBy(op.desc('score'))
            .joinDoc('doc', op.fragmentIdCol('fragmentId'))
            .orderBy(op.desc('score'));
}

Please note that if you have other Optic functions following op.fromSearchDocs, it may change the ordering of the results.
