i developing custom request handler using solr api. reference taking "morelikethis" reference.

i able access document using "getdoclist" api , taking object of "iterator" gives me document id .

how can access each field of document ??

well got answer .. here code me each field..

package org.apache.solr.handler.ext;   public class myrequesthandler extends requesthandlerbase{   @override   public void handlerequestbody(solrqueryrequest req, solrqueryresponse rsp)       throws exception {      system.out.println("i in handler");      /**      *  working core      */     solrcore core = req.getcore();     system.out.println("core " + "" + core.getdescription());     system.out.println("data directory " + "" + core.getdatadir());     system.out.println("index directory " + "" + core.getindexdir());       /**      *  working schema      */     indexschema schema = core.getschema();     schemafield field = schema.getfield("country");      system.out.println(field.isrequired());      /**      *  create map      */      indexschema schemaobj = req.getschema();      map<string , schemafield>map = req.getschema().getfields();      // iterate on keys     (string str : map.keyset()){         system.out.println(str);     }      // iterate on schemafield      (schemafield schemafieldobj: map.values()){          system.out.println(schemafieldobj.isrequired());     }      /**      *  find unique key field      */      field = schemaobj.getuniquekeyfield();     system.out.println(field.getname());      system.out.println(schemaobj.getqueryparserdefaultoperator());        /**      *   working request parameters      */      solrparams reqparams = req.getparams();     string q = reqparams.get(commonparams.q);     system.out.println(reqparams.get(commonparams.q));      string deftype = reqparams.get(queryparsing.deftype , qparserplugin.default_qtype);     system.out.println(deftype);       /**      *  working qparser      */     qparser queryparser = qparser.getparser(q, deftype, req);     query query = queryparser.getquery();       /**      *   searcher       */      solrindexsearcher indexsearcher = req.getsearcher();     indexreader reader = indexsearcher.getindexreader();     doclist matchdocs = indexsearcher.getdoclist(query, null, null, 1, 100000,10000);      // number of documents matched     system.out.println(matchdocs.matches());     // iterator         // documentreader      document doc;     string[] docfields;      dociterator iterator = matchdocs.iterator();     while (iterator.hasnext()){     integer id = iterator.nextdoc();     system.out.println("here " + id);     doc = reader.document(id);     docfields = doc.getvalues("state");      for(int i=0;i<docfields.length;i++){         system.out.println(docfields[i]);     }      }  }    @override   public string getdescription() {     return "my search handler";   }    @override   public string getsource() {     return "$source$";   }     @override   public string getversion() {     return "$revision$";   }  }

well in short, access document need "reader" object of "indexreader" class 'reader' call method 'getvalues(' field name')' . return array of strings.

Image
if set mycoolbar.fixedorder true,only grip on first band hidden. well,if use delphi 7 create vcl forms application,then put coolbar on , create 3 coolbans hold other controls,only grip , top coolbands can hidden setting mycoolbar.fixedorder:=true. i've uploaded picture make things clear. you got fixedorder property wrong. fixed property not allow bands rearranged if set true . setting property of coolbar true keep user changing bands order @ runtime, user can still move , resize bands. can give advice can do, actual solution problem, well, have wait answer. my advice use 3 coolbars in row , setting "fixedorder" property true , bandborderstyle bsnone . way grip hidden on of them. about property, it's not bug of ide, actual preference of property.
