EasyNet.Solr(http://easynet.codeplex.com)是由本人开发的 solr(http://lucene.apache.org/solr)c#客户端。它具有以下特性:
1.支持solr 3.1(不兼容solr 1.4.x) 2. 默认支持solr最高效的javabin协议 3.基于接口的序列化和反序列化协议,没有采用反射 4. 可以在架构基础上方便扩展处理solr支持的其他协议,如xml,json等等
以下是基本的使用示例: 索引和检索用到的实体类 Indexing and retrieval of entity class used public class Example { public string Id { get; set; } public string Name { get; set; } } 创建索引 Create index 序列化实现 Implement serialization public class ExampleObjectSerializer : IObjectSerializer<Example> { public IList<SolrInputDocument> Serializer(IEnumerable<Example> objs) { IList<SolrInputDocument> docs = new List<SolrInputDocument>(); foreach (Example obj in objs) { SolrInputDocument doc = new SolrInputDocument(); doc.Add("Id", new SolrInputField("id", obj.Id)); doc.Add("name", new SolrInputField("name", obj.Name)); docs.Add(doc); } return docs; } } 索引 Index ICodecFactory codecFactory = new BinaryCodecFactory(); ISolrConnection<NamedList> con = new SolrConnection<NamedList>("http://localhost:8088/solr"); IUpdateOperationParametersConvert<NamedList> updateOpParametersConvert = new BinaryUpdateOperationParametersConvert(); ISolrResponseParser<NamedList, ResponseHeader> responseHeaderParser = new BinaryResponseHeaderParser(); ISolrUpdateOperations<NamedList> updateOp = new SolrUpdateOperations<NamedList>(con, updateOpParametersConvert); IList<Example> examples = new List<Example>(); examples.Add(new Example() { Id = "16", Name = "Terry" + DateTime.Now.ToLongTimeString() }); examples.Add(new Example() { Id = "18", Name = "Terry" + DateTime.Now.ToLongTimeString() }); examples.Add(new Example() { Id = "17", Name = "Terry" + DateTime.Now.ToLongTimeString() }); IObjectSerializer<Example> objectSerializer = new ExampleObjectSerializer(); IList<SolrInputDocument> docs = objectSerializer.Serializer(examples); AddOptions? addOptions = new AddOptions() { CommitWithin = 10 }; CommitOptions? commitOptions = new CommitOptions() { WaitFlush = true, WaitSearcher = true }; OptimizeOptions? optimizeOptions = new OptimizeOptions() { WaitFlush = true, WaitSearcher = true }; NamedList addRes = updateOp.Add(docs, null, commitOptions, optimizeOptions); ResponseHeader responseHeader = responseHeaderParser.Parser(addRes); 查询 Query 反序列实现 Implement deserialize public class ExampleObjectDeserialize : IObjectDeserialize<Example> { public IEnumerable<Example> Deserialize(SolrDocumentList result) { IList<Example> examples = new List<Example>(); foreach (SolrDocument doc in result) { examples.Add(new Example() { Id = doc["id"].ToString(), Name = doc["name"].ToString() }); } return examples; } } 查询 Query ISolrConnection con = new SolrConnection("http://localhost:8088/solr"); IObjectDeserialize<Example> objectDeserialize = new ExampleObjectDeserialize(); ISolrResponseParser<NamedList, QueryResults<Example>> qrp = new BinaryQueryResultsParser<Example>(objectDeserialize); ISolrQueryOperations<NamedList> qop = new SolrQueryOperations<NamedList>(con); NameValueCollection options = new NameValueCollection(); options.Add(CommonParams.START, "0"); options.Add(CommonParams.ROWS, "10"); NamedList res = qop.Query(SolrQuery.All, options); QueryResults<Example> exps = qrp.Parser(res); |
