扩展 Umbraco 后台搜索以搜索自定义属性而不仅仅是标题

Question

我想做的是能够在后台搜索中输入自定义属性。例如将 ISBN 放入搜索字段并显示当前结果 returns“未找到任何项目”，因为搜索将仅显示标题节点的结果。

如何启用图中所示的内容搜索来搜索自定义字段中的数据？

数据在内部索引中，我已经检查了索引是否正常工作，如果我通过自定义数据搜索，可以在“检查管理”中看到结果。

解决方案是我用来扩展搜索的 https://dev.to/skttl/how-to-customize-searching-in-umbraco-list-views-1knk

在 App_Code (SearchExtender)

中添加一个新文件

using System.Linq;
using Examine;
using Umbraco.Core;
using Umbraco.Core.Cache;
using Umbraco.Core.Configuration;
using Umbraco.Core.Logging;
using Umbraco.Core.Models;
using Umbraco.Core.Persistence;
using Umbraco.Core.Persistence.DatabaseModelDefinitions;
using Umbraco.Core.PropertyEditors;
using Umbraco.Core.Services;
using Umbraco.Web;
using Umbraco.Web.Editors;
using Umbraco.Web.Models.ContentEditing;

namespace SearchExtender
{
    public class CustomListViewSearchController : ContentController
    {
        public CustomListViewSearchController(PropertyEditorCollection propertyEditors, IGlobalSettings globalSettings, IUmbracoContextAccessor umbracoContextAccessor, ISqlContext sqlContext, ServiceContext services, AppCaches appCaches, IProfilingLogger logger, IRuntimeState runtimeState, UmbracoHelper umbracoHelper)
            : base(propertyEditors, globalSettings, umbracoContextAccessor, sqlContext, services, appCaches, logger, runtimeState, umbracoHelper)
        {
        }

        public PagedResult<ContentItemBasic<ContentPropertyBasic>> GetChildrenCustom(int id, string includeProperties, int pageNumber = 0, int pageSize = 0, string orderBy = "SortOrder", Direction orderDirection = Direction.Ascending, bool orderBySystemField = true, string filter = "", string cultureName = "")
        {
            // get the parent node, and its doctype alias from the content cache
            var parentNode = Services.ContentService.GetById(id);
            var parentNodeDocTypeAlias = parentNode != null ? parentNode.ContentType.Alias : null;

            // if the parent node is not "books", redirect to the core GetChildren() method
            if (parentNode?.ContentType.Alias != "books")
            {
                return GetChildren(id, includeProperties, pageNumber, pageSize, orderBy, orderDirection, orderBySystemField, filter);
            }

            // if we can't get the InternalIndex, redirect to the core GetChildren() method, but log an error
            if (!ExamineManager.Instance.TryGetIndex("InternalIndex", out IIndex index))
            {
                Logger.Error<CustomListViewSearchController>("Couldn't get InternalIndex for searching products in list view");
                return GetChildren(id, includeProperties, pageNumber, pageSize, orderBy, orderDirection, orderBySystemField, filter);
            }

            // find children using Examine

            // create search criteria
            var searcher = index.GetSearcher();
            var searchCriteria = searcher.CreateQuery();
            var searchQuery = searchCriteria.Field("parentID", id);

            if (!filter.IsNullOrWhiteSpace())
            {
                searchQuery = searchQuery.And().GroupedOr(new [] { "nodeName", "isbn" }, filter);
            }

            // do the search, but limit the results to the current page  https://shazwazza.com/post/paging-with-examine/
            // pageNumber is not zero indexed in this, so just multiply pageSize by pageNumber
            var searchResults = searchQuery.Execute(pageSize * pageNumber);

            // get the results on the current page
            // pageNumber is not zero indexed in this, so subtract 1 from the pageNumber
            var totalChildren = searchResults.TotalItemCount;
            var pagedResultIds = searchResults.Skip((pageNumber > 0 ? pageNumber - 1 : 0) * pageSize).Select(x => x.Id).Select(x => int.Parse(x)).ToList();
            var children = Services.ContentService.GetByIds(pagedResultIds).ToList();

            if (totalChildren == 0)
            {
                return new PagedResult<ContentItemBasic<ContentPropertyBasic>>(0, 0, 0);
            }

            var pagedResult = new PagedResult<ContentItemBasic<ContentPropertyBasic>>(totalChildren, pageNumber, pageSize);
            pagedResult.Items = children.Select(content =>
                Mapper.Map<IContent, ContentItemBasic<ContentPropertyBasic>>(content))
                .ToList(); // evaluate now

            return pagedResult;

        }
    }
}

更改 /umbraco/backoffice/UmbracoApi/Content/GetChildren 的请求（子节点的默认端点），并将其更改为我新创建的，位于 /umbraco/backoffice/api/CustomListViewSearch/GetChildrenCustom.

这很容易通过添加一个包含这样的拦截器的 js 文件来完成。将文件添加到 /App_Plugins/CustomListViewSearch/CustomListViewSearch.js

angular.module('umbraco.services').config([
   '$httpProvider',
   function ($httpProvider) {

       $httpProvider.interceptors.push(function ($q) {
           return {
               'request': function (request) {

                   // Redirect any requests for the listview to our custom list view UI
                   if (request.url.indexOf("backoffice/UmbracoApi/Content/GetChildren?id=") > -1)
                       request.url = request.url.replace("backoffice/UmbracoApi/Content/GetChildren", "backoffice/api/CustomListViewSearch/GetChildrenCustom");

                   return request || $q.when(request);
               }
           };
       });

   }]);

我的 App_Plugins 文件夹中有一个 package.manifest 文件。

{
  "javascript": [
    "/App_Plugins/CustomListViewSearch/CustomListViewSearch.js"
  ]
}

如果节点 Alais 不工作，请确保它在文档类型中设置（文档类型名称最右侧）
