MarkLogic Node.js。 如何在结果中指定返回属性

Question

How can I specify returned fields in my query so that I can avoid large data in my response. For example I have a json like this and I want only summary in response:

{
   foo:"bar",
   summary:"my summary",
   other:[
      {key: "random thing", value: 5},
      {key: "another random", value: 3}
   ]
}

var ml = require('marklogic');
var conn = require('./config.js').connection;
var db = ml.createDatabaseClient(conn);
var qb = ml.queryBuilder;

db.documents.query(
  qb.where(
    qb.collection('test')   
  )
  .withOptions({metrics: true})
).result()
.then(function(docs) {
  console.log('This search found: ' + JSON.stringify(docs[1]));
})
.catch(function(error) {
  console.log('something went wrong: ' + error);
});

Here are a couple of options:

• Install a transform and transform the documents on the server; see:

• Specify paths to extract from the documents:
