扩展 Umbraco 后台搜索以搜索自定义属性，而不仅仅是标题

如何解决扩展 Umbraco 后台搜索以搜索自定义属性，而不仅仅是标题

我想做的是能够在后台搜索中键入自定义属性。例如将 ISBN 放入搜索字段并显示当前结果，它始终返回“未找到项目”，因为搜索将仅显示标题节点的结果。

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

解决方法

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,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);
            }

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

            return pagedResult;

        }
    }
}

更改 /umbraco/backoffice/UmbracoApi/Content/GetChildren（子节点的默认端点）的请求，并将其更改为我新创建的一个，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 文件夹中的 package.manifest 文件。

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

如果节点 Alais 不工作，请确保其设置在文档类型中（文档类型名称的最右侧）
