High-performance solr c # client easynet. SOLR

Easynet. SOLR (http://easynet.codeplex.com) is a SOLR (http://lucene.apache.org/solr) C # client developed by myself. It has the following features:

 

1. Support for SOLR 3.1 (not compatible with SOLR 1.4.x)

2. By default, SOLR's most efficient javabin protocol is supported.

3. The interface-based serialization and deserialization protocols are not reflected.

4. other protocols supported by SOLR, such as XML and JSON, can be easily extended based on the architecture.

 

The following is a basic example:

Indexing and retrieval of entity class used

Public Class Example
{
Public String ID {Get; set ;}
Public string name {Get; set ;}
}

Serialization for 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;
}
}

Isolrconnection <namedlist> con = new solrconnection <namedlist> ("http: // localhost: 8088/SOLR ");

Implement implement deserialize in Reverse Sequence

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;
}
}

Query

Isolrconnection con = new solrconnection ("http: // localhost: 8088/SOLR ");
