Searching dates at Lucene 1.4.3 webindex
|
|
Hi all,
First, thanks a lot Patrick and Grant, you were very very helpful in my last
question! Here comes the final code. The file should have ":" as delimiters
at the files to identify the fields, to work. e.g.:
File.txt
:Title: Web searching in Lucene
:Description: This article presents the results of using a webservice
running Lucene search
:Author: Eder Reboucas
:Content: bla bla bla... etc. e tal
try {
Scanner scanner = new Scanner(f);
scanner.useDelimiter("\\s*:\\s*"); // whitespace and ":"
String campo_nome = new String();
String campo_cont = new String();
while (scanner.hasNext()) {
campo_nome = (campo_nome + scanner.next());
campo_cont = (campo_cont + scanner.next());
doc.add(new Field(campo_nome,campo_cont,true,true,true));
System.out.println("Field Name: " + campo_nome + "\nContent: " +
campo_cont);
campo_nome = "";
campo_cont = "";
}
scanner.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
}
I tried to create a String field getting date, or a Date Field to search in
the lucene 1.4.3 lucene web demo, by two ways:
I) Using doc.add(Field.Keyword("modified",
DateField.timeToString(f.lastModified())));
When I try to print it, it returns "0etut1c5k".
II) Using Date Data = new Date ( f.lastModified() );
String arq_data = Data.toLocaleString();
arq_data = arq_data.replaceAll("/","");
arq_data = arq_data.substring(0,8);
doc.add(new Field("Data", arq_data, true, true, true));
When I try to print it, it returns "28102006" - the date.
But when I try to search it by the query "Data: 28102006", it doesn't return
the file.
So, I got the following questions:
I - What does the Field.KeyWord method returns?
II - Would somebody help me exaplining how to turn a date search / indexing
reality in my job?
Great hughes
Eder
