用于在MarkLogic

Question

var marklogic=require('marklogic');
var ins=marklogic.createDatabaseClient({'host':'localhost','port':'7010','user':'admin','password':'admin',});
var qb=marklogic.queryBuilder;
ins.documents.query(
  qb.propertiesFragment(
    qb.value("Author","Akhilesh Sabbisetti"))
  ).result(function(matches){
    matches.forEach(function(match){
      console.log(match.uri);
    });
  });

上面的代码应该仅适用于文档的属性，但它不能像那样工作。我得到了无关紧要的结果。请更正我的代码......

您错过了qb.where()方法：

var marklogic=require('marklogic');
var ins=marklogic.createDatabaseClient({'host':'localhost','port':'7010','user':'admin','password':'admin',});
var qb=marklogic.queryBuilder;
ins.documents.query(
qb.where(
  qb.propertiesFragment(
    qb.value("Author","Akhilesh Sabbisetti"))
  )
).result(function(matches){
    matches.forEach(function(match){
      console.log(match.uri);
    });
  });

我还建议您使用以下格式的promise promise处理模式，并允许捕获错误：

db.documents.query(
  qb.where(
    qb.propertiesFragment(
      qb.value('Author', 'Akhilesh Sabbisetti')
    )
  )
)
.result()
.then(function(matches) {
  console.log(matches);
})
.catch(function(error) {
  console.log(error);
});
