如何用.net代码执行亚马逊云搜索
本文关键字:亚马逊 搜索 执行 代码 何用 net | 更新日期: 2023-09-27 18:09:55
我正在学习亚马逊云搜索,但我在c#或Java中找不到任何代码(虽然我在c#中创建,但如果我能在Java中获得代码,那么我可以尝试在c#中转换)。
这只是我在c#中发现的1个代码:https://github.com/Sitefinity-SDK/amazon-cloud-search-sample/tree/master/SitefinityWebApp.
这是我在这段代码中找到的一个方法:
public IResultSet Search(ISearchQuery query)
{
AmazonCloudSearchDomainConfig config = new AmazonCloudSearchDomainConfig();
config.ServiceURL = "http://search-index2-cdduimbipgk3rpnfgny6posyzy.eu-west-1.cloudsearch.amazonaws.com/";
AmazonCloudSearchDomainClient domainClient = new AmazonCloudSearchDomainClient("AKIAJ6MPIX37TLIXW7HQ", "DnrFrw9ZEr7g4Svh0rh6z+s3PxMaypl607eEUehQ", config);
SearchRequest searchRequest = new SearchRequest();
List<string> suggestions = new List<string>();
StringBuilder highlights = new StringBuilder();
highlights.Append("{''");
if (query == null)
throw new ArgumentNullException("query");
foreach (var field in query.HighlightedFields)
{
if (highlights.Length > 2)
{
highlights.Append(", ''");
}
highlights.Append(field.ToUpperInvariant());
highlights.Append("'':{} ");
SuggestRequest suggestRequest = new SuggestRequest();
Suggester suggester = new Suggester();
suggester.SuggesterName = field.ToUpperInvariant() + "_suggester";
suggestRequest.Suggester = suggester.SuggesterName;
suggestRequest.Size = query.Take;
suggestRequest.Query = query.Text;
SuggestResponse suggestion = domainClient.Suggest(suggestRequest);
foreach (var suggest in suggestion.Suggest.Suggestions)
{
suggestions.Add(suggest.Suggestion);
}
}
highlights.Append("}");
if (query.Filter != null)
{
searchRequest.FilterQuery = this.BuildQueryFilter(query.Filter);
}
if (query.OrderBy != null)
{
searchRequest.Sort = string.Join(",", query.OrderBy);
}
if (query.Take > 0)
{
searchRequest.Size = query.Take;
}
if (query.Skip > 0)
{
searchRequest.Start = query.Skip;
}
searchRequest.Highlight = highlights.ToString();
searchRequest.Query = query.Text;
searchRequest.QueryParser = QueryParser.Simple;
var result = domainClient.Search(searchRequest).SearchResult;
//var result = domainClient.Search(searchRequest).SearchResult;
return new AmazonResultSet(result, suggestions);
}
我已经使用AWS控制台在Amazon Cloud Search中创建了域,并使用Amazon预定义配置选项上传了文档,该选项是Amazon提供的用于演示的movie Imdb json文件。
但是在这个方法中,我不知道如何使用这个方法,就像如果我想搜索Director name那么我如何传递这个方法,因为这个方法参数的类型是ISearchQuery?
我建议使用官方AWS CloudSearch . net SDK。你正在看的库看起来不错(尽管我没有看到任何细节),但官方版本更有可能在发布后立即暴露新的CloudSearch功能,如果你需要与AWS支持人员交谈,将会得到支持,等等。
具体来说,看一下SearchRequest类——它的所有参数都是字符串,所以我认为这就消除了你关于ISearchQuery的问题。
我在。net中找不到一个查询的例子,但这显示有人使用AWS。net SDK上传文档。它本质上与查询过程相同:创建和配置Request对象并将其传递给客户端。
编辑:既然你还是觉得困难,我给你举个例子。请记住,我不熟悉c#,也没有尝试运行或甚至编译这个,但我认为它至少应该接近工作。它基于在http://docs.aws.amazon.com/sdkfornet/v3/apidocs/
查看文档// Configure the Client that you'll use to make search requests
string queryUrl = @"http://search-<domainname>-xxxxxxxxxxxxxxxxxxxxxxxxxx.us-east-1.cloudsearch.amazonaws.com";
AmazonCloudSearchDomainClient searchClient = new AmazonCloudSearchDomainClient(queryUrl);
// Configure a search request with your query
SearchRequest searchRequest = new SearchRequest();
searchRequest.Query = "potato";
// TODO Set your other params like parser, suggester, etc
// Submit your request via the client and get back a response containing search results
SearchResponse searchResponse = searchClient.Search(searchRequest);
