Can't locate field
This is my first message to this list. I have successfully created several little tests of the Lucene api. In my last test, I am trying to index "data records". Only the "primary key" needs to be stored (and I did not even index this field). For the others I want to index, but neither store or tokenize (I want the the entire text string to be the "term").
So my index code looks like:
doc.add(Field.UnIndexed("userid", dtable[i][iuserid]));
doc.add(new Field("charge",dtable[i][icharge],false,true,false));
doc.add(new Field("fname", dtable[i][ifname],false,true,false));
doc.add(new Field("lname", dtable[i][ilname],false,true,false));
doc.add(new Field("email", dtable[i][iemail],false,true,false));
doc.add(new Field("hiredt",dtable[i][ihiredt],false,true,false));
doc.add(new Field("title", dtable[i][ititle],false,true,true));
The last field I tokenize and it seems to work ok. The others never return hits.
My search code is below. Essentially I am trying to search like this:
java ./index lname smith
Which should find everyone with a last name of "smith". But no hits are returned.
What am I doing wrong?
Thanks
public class Search {
public static void main(String[] args) throws Exception {
Date start = new Date();
String indexPath = args[0], qfield = args[1], queryString = args[2];
Searcher searcher = new IndexSearcher(indexPath);
Query query = QueryParser.parse(queryString, qfield,
new SimpleAnalyzer());
Hits hits = searcher.search(query);
Date stop = new Date();
if ( args.length > 2 ) {
for (int i=0; i<hits.length(); i++) {
System.out.println(
"Userid "+hits.doc(i).get("userid") +
"; Score: " +
hits.score(i));
};
}
System.out.println("\nNumber of hits: "+ hits.length());
long totalms = stop.getTime() - start.getTime();
System.out.println(totalms + " total milliseconds");
}
}

here is the full indexing code. and it does use the SimpleAnalyzer.
thanks for your help!
import java.io.File;
import java.io.IOException;
import java.io.OutputStream;
import java.util.*;
import org.apache.lucene.analysis.SimpleAnalyzer;
import org.apache.lucene.index.IndexWriter;
import org.apache.lucene.document.*;
public class Indexer {
public static void main(String[] args) {
String indexLoc = "./index";
int iuserid = 0;
int icharge = 1;
int ifname = 2;
int ilname = 3;
int iemail = 4;
int ihiredt = 5;
int ititle = 6;
// store index token
IndexWriter writer;
Date start = new Date();
try {
writer = new IndexWriter(indexLoc, new SimpleAnalyzer(), false);
String data = StringHelper.fileToString("u2info.txt");
String[][] dtable = StringHelper.toTable(data,"\n","|");
for ( int i=0; i < dtable.length; i++ ) {
org.apache.lucene.document.Document doc =
new org.apache.lucene.document.Document();
// add userid as unindexed - can't search, but it is stored
// so this is like an oid.
doc.add(Field.UnIndexed("userid", dtable[i][iuserid]));
// add others as follows:
// a. don't store (can't retrieve value)
// b. do index (ie, can search on the value)
// c. don't tokenize, just use whole field as-is
doc.add(new Field("charge",dtable[i][icharge],false,true,false));
doc.add(new Field("fname", dtable[i][ifname],false,true,false));
doc.add(new Field("lname", dtable[i][ilname],false,true,false));
doc.add(new Field("email", dtable[i][iemail],false,true,false));
doc.add(new Field("hiredt",dtable[i][ihiredt],false,true,false));
// on this one, tokenize the title so that it can be
// text content searched.
doc.add(new Field("title", dtable[i][ititle],false,true,true));
writer.addDocument(doc);
}
writer.close();
} catch (Exception e) {
e.printStackTrace();
}
System.out.println("Started at "+start.toString());
Date stop = new Date();
System.out.println("Stopped at "+stop.toString());
}
}

Re: Can't locate field
Posted by Ian Lea <ia...@blackwell.co.uk>.
Are you using the same Analyzer (SimpleAnalyzer) when adding
data to the index? You don't show us the full indexing code.
