Sitecore HOWTO:搜索具有特定值的项目的项目桶

Question

我有一个物品桶里面有超过30 000个物品.我需要的是快速搜索具有特定字段设置为特定值的项目,或者更好的是制作类似SELECT WHERE fieldValue IN(1,2,3,4)语句的内容.有没有现成的解决方案？我在网上搜索过,我发现的唯一一件事是"项目桶和搜索的开发人员指南",但没有代码示例.

Answer 1

你需要这样的东西.Bucket项目是IIndexable,因此可以使用Sitecore 7搜索API进行搜索.

下面的代码片段可以很容易地进行调整以满足您的需求,这只是修改where子句的问题.如果您需要有关sitecore 7语法的任何进一步帮助,请在下面的QuickStart博客文章上写评论,我会回来给你.

var bucketItem = Sitecore.Context.Database.GetItem(bucketPath);
  if (bucketItem != null && BucketManager.IsBucket(bucketItem))
  {     
     using (var searchContext = ContentSearchManager.GetIndex(bucketItem as IIndexable).CreateSearchContext())
    {
        var result = searchContext.GetQueryable<SearchResultItem().Where(x => x.Name == itemName).FirstOrDefault();
        if(result != null)
            Context.Item = result.GetItem();
    }
  }

Answer 2

使用Sitecore内容编辑器:

转到存储区项目,然后在搜索选项卡中,开始键入以下内容(将fieldname和value替换为实际字段名称和值):

自定义:字段名|值

然后按回车键,您会看到查询结果,如果需要,您可以一次查看多个查询.

使用Sitecore内容搜索API:

using Sitecore.ContentSearch;
using Sitecore.ContentSearch.Linq;
using Sitecore.ContentSearch.SearchTypes;
using Sitecore.ContentSearch.Linq.Utilities

ID bucketItemID = "GUID of your bucket item";
ID templateID = "Guid of your item's template under bucket";
string values = "1,2,3,4,5";

using (var context = ContentSearchManager.GetIndex("sitecore_web_index").CreateSearchContext())
{
    var predicate = PredicateBuilder.True<SearchResultItem>();
    predicate = PredicateBuilder.And(item => item.TemplateId == new ID(templateID) 
                                     && item.Paths.Contains(bucketItemID));
    var innerPredicate = PredicateBuilder.False<SearchResultItem>();
    foreach(string val in values.Split(','))
    {
         innerPredicate = PredicateBuilder.False<SearchResultItem>();
         innerPredicate = innerPredicate.Or(item => item["FIELDNAME"] == val);
    }
    predicate = predicate.And(innerPredicate);

    var result = predicate.GetResults();
    List<Item> ResultsItems = new List<Item>();
    foreach (var hit in result.Hits)
    {
       Item item = hit.Document.GetItem();
       if(item !=null)
       {
          ResultsItems .Add(item);
       }
    }
}
