cts.search operation.
If this parameter is omitted, the context node is used.
This function returns
a JavaScript object that contains
details about the
score computation only if the following conditions are met:
The node parameter or context node is the result
of a
cts.search call that
included the relevance-trace option; and the score is
non-zero. For
example, you will not get a report if you use the score-zero
option on your
cts.search, if the
search returns no results, or if node is not the result
of
cts.search.
The score computation reflects the scoring method specified in the
cts.search expression,
if any. The score-zero and score-random
methods do not generate a report.
Collecting score computation details with which to generate this report
is costly, so using the relevance-trace option will
slow down your search significantly.
var x = cts.search("dog", ["relevance-trace"]).toArray();
cts.relevanceInfo(x[0]);
