You can put weights on the cts:query constructors to affect how much a match in
each constructor contributes to score. You can also change the word query
configuration on the database to boost the weight for a particular element
(like title, for example). The word query configuration change bakes that
weight into the index.
To accomplish the cts:query weight boost, you might create a query that
combines word-query and element-word-query with an and-query of a word-query
and an or-query (so you keep the semantics the same as just the word-query),
with a weight on the element-word-query. Something like:
cts:and-query((
cts:word-query($q),
cts:or-query((
cts:element-word-query(xs:QName("title"), $q, (), 16) ))
))
This would boost the score of matches that occur in title elements.
For more details about relevance, see "Relevance Scores: Understanding and
Customizing" chapter in the Search Developer's Guide.

Subject: [MarkLogic Dev General] relevance by element/attribute values
For a given query, is there a way to indicate field1 (title) has higher weight
compared to other fields (body-text) for search relevance.
i.e.
Query: "New York"
Doc1- has "New York" in <bodytext> 3 times
Doc2- has "New York" in <title> once
(where <bodytext> or <title> may have more elements within it.)
How do I do search:search to get result in such order that Doc-2 appears first
(even though it has less hits for the query terms).
Thanks.
