SOLR configuration and simple demo

Introduction:

SOLR is an enterprise-level full-text search engine based on Lucene Java Search Library. It is currently a project of Apache. Its official website is in http://lucene.apache.org/solr. SOLR needs to run in a servlet container, such as Tomcat. SOLR provides HTTP/XML-based Web Services at the upper layer of Lucene. Our applications need to interact with SOLR through this service.

 

 

Premise: Download tomcat. Omitted.

Step 1: Download SOLR, http://www.apache.org/dyn/closer.cgi/lucene/solr/

I downloaded version 3.5 and decompressed It To The edisk. E:/apache-solr-3.5.0

 

Step 2: Modify conf \ Server. xml and modify the line of port 8080 as follows:

 

<Connector port="8080" protocol="HTTP/1.1"  
           connectionTimeout="20000"  
           redirectPort="8443" URIEncoding="UTF-8"/> 

The following is also useful.

<Connector port="8080" URLEncoder="UTF-8" redirectPort="8443" connectionTimeout="20000" protocol="HTTP/1.1"/>

In fact, it is added the uriencoding = "UTF-8" configuration. The first method is recommended. The two differences are unknown for the moment.

 

Step 3: Configure SOLR

Add the Catalina \ localhost \ SOLR. xml file in the conf directory. If the conf Folder does not contain Catalina, create it.

SOLR. XML content:

<Context docBase="E:/apache-solr-3.5.0/dist/apache-solr-3.5.0.war" debug="0" crossContext="true" >
<Environment name="solr/home" type="java.lang.String" value="E:/apache-solr-3.5.0/example/solr" override="true" /></Context>  

Step 4: start Tomcat. Enter http: // localhost: 8080/SOLR/to display the welcome page, indicating that the interface is successful.

 

Step 5: simple Java API operations

Refer to the http://www.iteye.com/topic/315330 to write in detail.

The complete code for reading and writing data is as follows:

Package com. weishangye. Test. SOLR;

Import java. util. arraylist;
Import java. util. collection;
Import java. util. iterator;
Import org. Apache. SOLR. Client. solrj. solrquery;
Import org. Apache. SOLR. Client. solrj. solrserver;
Import org. Apache. SOLR. Client. solrj. impl. commonshttpsolrserver;
Import org. Apache. SOLR. Client. solrj. response. queryresponse;
Import org. Apache. SOLR. Common. solrdocument;
Import org. Apache. SOLR. Common. solrdocumentlist;
Import org. Apache. SOLR. Common. solrinputdocument;

Public class solrtest1 {

Public static void main (string [] ARGs) throws exception {
String url = "http: // localhost: 8080/SOLR ";
Solrserver Server = new commonshttpsolrserver (URL );
Server. deletebyquery ("*: *"); // delete everything!
Solrinputdocument doc1 = new solrinputdocument ();
Doc1.addfield ("ID", "id1", 1.0f );
Doc1.addfield ("name", "doc1", 1.0f );
Doc1.addfield ("price", 10 );
        
Solrinputdocument doc2 = new solrinputdocument ();
Doc2.addfield ("ID", "ID2", 1.0f );
Doc2.addfield ("name", "", 1.0f );
Doc2.addfield ("price", 20 );
        
Collection <solrinputdocument> docs = new arraylist <solrinputdocument> ();
Docs. Add (doc1 );
Docs. Add (doc2 );
Server. Add (DOCS );
Server. Commit ();
        
Solrquery query = new solrquery ();
Query. setquery ("*:*");
Query. addsortfield ("price", solrquery. Order. DESC );
Queryresponse RSp = server. Query (query );
Solrdocumentlist docslist = RSP. getresults ();
For (iterator <solrdocument> Doc = docslist. iterator (); Doc. hasnext ();){
Solrdocument d = Doc. Next ();
System. Out. Print (D. getfieldvalue ("ID") + "-> ");
System. Out. println (D. getfieldvalue ("name "));
}
}

}
