                <!--define IK parts-to-               <fieldtype name= "Text_ik" class= "SOLR. TextField ">                   <!--the word breaker at index time--                   <analyzer type=" index "ismaxwordlength=" false "class=" Org.wltea.analyzer.lucene.IKAnalyzer "/>                   <!--word breaker--                   <analyzer type=" Query " Ismaxwordlength= "true" class= "Org.wltea.analyzer.lucene.IKAnalyzer"/>               </fieldType>               <field Name= "id" type= "string" indexed= "true" stored= "true" required= "true" multivalued= "false"/>                <field name= " Username "type=" Text_ik "indexed=" true "stored=" true "multivalued=" true "/>               <field name=" age "type=" Text_ik "Indexed=" true "stored=" true "/>               <field name=" keywords "type=" Text_ik "indexed=" true "stored=" true "/>


3.2 Adding the IK word breakers libraryfiled is used in the definition of Ikanalyzer, need to enter the relevant configuration reference word breakerA. Adding Ikanalyzer3.2.8.jar:http://download.csdn.net/detail/buyaor in Solr-5.2.1/contrib/analysis-extras/lib e_wo/8946777B. Add the Library Reference configuration in Solrconfig.xml (/solr-5.2.1/server/solr/user/conf), as follows                     
<lib dir= "${solr.install.dir: /.. /.. /..} /contrib/analysis-extras/lib "regex=". *\.jar "/>

    4. Adding index data using SOLRJ       
/** * Add document */@Testpublic void Adddoc () {solrinputdocument doc = new solrinputdocument ();d Oc.addfield ("id", "page");d OC.ADDF Ield ("username", "haha");d Oc.addfield ("keywords", "haha hello");d Oc.addfield ("Age", "18"); Updateresponse Response;try {response = Httpsolrclient.add (/* "User", */doc);//Submit httpsolrclient.commit ();// Logger.info ("########## Query Time:" + response.getqtime ()); System.out.println ("########## Query Time:" + response.getqtime ());//Logger.info ("########## Elapsed Time:" +//respon Se.getelapsedtime ()); System.out.println ("########## Elapsed Time:" + response.getelapsedtime ());//Logger.info ("########## Status:" + Response.getstatus ()); System.out.println ("########## Status:" + response.getstatus ());} catch (Solrserverexception e) {//Todo auto-generated catch Blocke.printstacktrace ();} catch (IOException e) {//Todo Auto -generated catch Blocke.printstacktrace ();}}

5. Querying Data    
@Testpublic void Testquery () {solrquery solrquery = new Solrquery ("keywords:* good");//Solrquery.setfilterqueries (" Resourcename:*analytics* "),//Solrquery solrquery = new Solrquery (" *:* ");//Solrquery.setfields (" id "," title "); Solrquery.setstart (0). Setrows (5); try {queryresponse queryresponse = httpsolrclient.query (/* "user", */solrquery);// Logger.info ("Results:" +//queryresponse.getresults (). Getnumfound ()); System.out.println ("Results:" + queryresponse.getresults (). Getnumfound ()); Solrdocumentlist solrdocumentlist = Queryresponse.getresults (); for (Solrdocument solrdocument:solrdocumentlist) { collection<string> FieldNames = Solrdocument.getfieldnames ();//Logger.info ("=============================== ==========="); System.out.println ("=========================================="); for (String field:fieldnames) {//Logger.info ( Field + ":" +//solrdocument.getfieldvalue (field)); System.out.println (Field + ":" + solrdocument.getfieldvalue (field));}}} catch (Solrserverexception e) {//TODO Auto-generated catch Blocke.printstacktrace ();} catch (IOException e) {//TODO auto-generated catch Blocke.printstacktrace ();}}


You may encounter the following exception Org.apache.solr.client.solrj.impl.httpsolrclient$remotesolrexception:error from server at http:// 192.168.0.12:8983/solr:expected MIME type application/xml but got text/html. <meta http-equiv= "Content-type" content= "text/html; Charset=utf-8 "/>
