Sitecore HOWTO: Search item bucket for items with specific values - search

Question

I have an item bucket with more then 30 000 items inside. What I need is to quickly search items that have particular field set to particular value, or even better is to make something like SELECT WHERE fieldValue IN (1,2,3,4) statement. Are there any ready solutions?
I searched the web and the only thing I found is "Developer's Guide to Item
Buckets and Search" but there is no code examples.

Answer 1

You need something like this. The Bucket item is an IIndexable so it can be searched using Sitecore 7 search API.
This code snippet below can easily be adapted to meet your needs and it's just a question of modifying the where clause.if you need any further help with the sitecore 7 syntax just write a comment on the QuickStart blog post below and I'll get back to you.
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();
}
}

Using Sitecore Content Editor:
Go to the bucket item then In search tab, start typing the following (replace fieldname and value with actual field name and value):
custom:fieldname|value
Then hit enter, you see the result of the query, you can multiple queries at once if you want.
Using Sitecore Content Search 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);
}
}
}
