您好，我是使用 MarkLogic 9 结合 NodeJS 进行查询的新手，并尝试使用 MarkLogic 9 示例中提到的 QBE（按示例查询）（https://docs.marklogic.com/guide/search-dev /qbe ) 当我使用带有以下语句的 xquery 时：

xquery version "1.0-ml";
declare namespace html = "http://www.w3.org/1999/xhtml";

let $items := fn:collection()/scope/item
for $i in $items
  let $sscc := $i/*:transaction/*:sscc/text()
  let $type:= $i/*:transaction/*:type/text()
  let $actorId := $i/*:transaction/*:actorId/text()
  let $device := $i/*:transaction/*:device/text()
  let $ordernummer := $i/*:order/*:orderNumber/text()
  where $ordernummer = 3788888
  return <td>{$sscc}</td>

返回 46 个正确结果。当我尝试使用 QBE 执行此操作时：

exports.postQuery = function(req, res) {


var queryInput = req.body.message
  console.info('Start postQuery!!!')
  console.info(queryInput)
  db.documents.query(
    //qb.where(qb.byExample(
    //  queryInput
    qb.byExample({
      $query: {
        orderNumber: {$word : '3788888'},
        $filtered: true
      },
      $format: 'json'
}))

它返回 10 个结果而不是 46 个。它与我使用哪个订单号无关，所有可能性都显示 10 条记录。你能告诉我我做错了什么吗？

MarkLogic 中的源 xml 文件采用以下格式：

在 MarkLogic 客户端页面中搜索结果列表中的请求。默认页面长度为 10 个结果。

To get more results, use the slice method to specify the length. To get all results, you can use the JavaScript MAX_SAFE_INTEGER constant:

qb.where(qb.byExample(...))
  .slice(0, Number.MAX_SAFE_INTEGER)
  .withOptions({search: ['filtered']})

Caveat: the practical approach for a large result set is to page instead of trying to get all of the results at once.

For more information, see:

http://docs.marklogic.com/jsdoc/queryBuilder.html#slice

Hoping that helps,
