可以在 MarkLogic JSearch 中使用持久搜索选项吗?

Can Persistent Search Options be Used in MarkLogic JSearch?

是否可以在 JSearch 中使用预定义的持久搜索选项,类似于搜索 REST API?翻阅文档,我无法找到它。

JSearch:https://docs.marklogic.com/guide/search-dev/javascript

查询选项:https://docs.marklogic.com/guide/search-dev/query-options

谢谢!

不直接。您将不得不遍历这些选项,并使用各个方面和您自己构建搜索。不过也不会太难。下面是一个快速尝试。我通过 GET /v1/config/query/all?format=json 下载了现有的搜索选项,并隔离了一些路径索引方面。这里有一些遍历它们并生成方面值的代码:

'use strict';

const jsearch = require('/MarkLogic/jsearch.sjs');

function reference(c) {
  if (c.range) {
    if (c.range['path-index']) {
      return cts.pathReference(c.range['path-index'].text)
    }
  }
}

const options = {
    "options": {
        "constraint": [{
            "name": "Auteur",
            "range": {
                "type": "xs:string",
                "facet": true,
                "collation": "http://marklogic.com/collation/codepoint",
                "facet-option": ["limit=10", "frequency-order", "descending"],
                "path-index": {
                    "text": "*:meta[@name = 'Author']/@content"
                }
            }
        }, {
            "name": "ContentType",
            "range": {
                "type": "xs:string",
                "facet": true,
                "collation": "http://marklogic.com/collation/codepoint",
                "facet-option": ["limit=10", "frequency-order", "descending"],
                "path-index": {
                    "text": "*:meta[@name = 'content-type']/@content"
                }
            }
        }]
    }
};

const facets = options.options.constraint.filter(c => c.range);

jsearch.facets(
  facets.map(f => {
    let ref = reference(f);
    if (ref) {
      return jsearch.facet(f.name, ref);
    }
  }).filter(f => f)
).result('iterator');

HTH!
