Never mind. Stupid, stupid assumption on my part with the data. Thanks anyway.

Erik, Thanks for reply. Some lists want all the info, some don't. Just thought I'd try to provide as much info as possible 8-) That being said, where do I find Luke?

Simplifying the example, besides making it easier for us to understand, would likely shed light on the problem. Everything (I think) indexes correctly. To be sure, try Luke out and see what got indexed exactly. You can also use Luke as an ad-hoc search tool rather than writing your own. When I search against this index, though, I get some weird results, especially when using an '*' at the end of my criteria. The results you got definitely are weird given the query, and in my initial glance through your code I did not see the issue pop out. Luke will likely shed much more light on the matter.

[newbie] Confused about PrefixQuery
All,
I'm investigating the use of Lucene as a search engine, and have been doing
some 'proof-of-concept' coding today. I'm indexing about 650 text files,
and then searching against them using QueryParser. Here's the indexing code
snippet:
public static void Result(IndexWriter indexWriter, File file)
throws FileNotFoundException
{
Document document = null;
String content = "";
BufferedReader br = new BufferedReader(new FileReader(file));
boolean EOF = false;
try
{
while(!EOF)
{
String s = (String) br.readLine();
if (null == s)
{
EOF = true;
}
else
{
if (!"".equals(s) &&
"CC>".equals(s.substring(0, 3)))
{
document = new Document();
document.add(Field.Text("account",
s.substring(3, 7)));
document.add(Field.Keyword("created", s.substring(s.indexOf("DC>") + 3,
s.indexOf("DC>") + 11)));
content = new String();
}
else if (!"".equals(s) &&
"AN>".equals(s.substring(0, 3)))
{
document.add(Field.Keyword("lastname", s.substring(3,
28).trim().toLowerCase()));
document.add(Field.Keyword("firstname", s.substring(28,
43).trim().toLowerCase()));
document.add(Field.Text("name",
s.substring(28, 43).trim() + " " + s.substring(3, 28).trim()));
document.add(Field.Keyword("controlnumber", s.substring(44, 52)));
document.add(Field.Keyword("status",
s.substring(52, 53).trim()));
document.add(Field.Keyword("ssn",
s.substring(53, 62)));
document.add(Field.Keyword("dob",
s.substring(62, 70)));
document.add(Field.Keyword("collected", s.substring(137, 145)));
}
else if (!"".equals(s) &&
"
The text files have two control lines at the beginning of them - CC> and
AN>. I extract particular fields from these lines and add them to my
document. Everything (I think) indexes correctly. When I search against
this index, though, I get some weird results, especially when using an '*'
at the end of my criteria. Here's the search code snippet:
public static void main(String[] args)
{
try
{
Searcher searcher = new IndexSearcher("c:\\ResultIndex");
Analyzer analyzer = new StandardAnalyzer();
BufferedReader br= new BufferedReader(new
InputStreamReader(System.in));
while(true)
{
System.out.println("Query: ");
String s = br.readLine();
if (null == s)
{
break;
}
else
{
Query query = QueryParser.parse(s,
"content", analyzer);
System.out.println("Searching for: " +
query.toString("content"));
Hits hits = searcher.search(query);
System.out.println("... Found " +
hits.length() + " matching documents");
System.out.println("");
for (int i = 0; i < hits.length(); i++)
{
Document document = hits.doc(i);
System.out.println("Hit " + i + ":
Specimen = " + document.get("controlnumber") + ", Account = " +
document.get("account") +
", Status = " +
document.get("status") + ", Name = " + document.get("name") + ", SSN = " +
document.get("ssn") +
", DOB = " +
document.get("dob") + ", Collected = " + document.get("collected") + ",
Created = " + document.get("created"));
//System.out.println(document.get("content"));
}
}
}
}
catch(Exception e)
{
System.out.println(e.getClass() + " caught with message " +
e.getMessage());
}
}
When I run this using a criteria string of
lastname:mar*
I get back the following:
Query:
lastname:mar*
Se
