hi sam
you can add content and time stamp field like this.
// add content
doc.add(new Field("contents", content,Field.Store.NO,Field.Index.ANALYZED);
// add timestamp
NumericField timestampField = new NumericField("timestamp");
timestampField.setLongValue(DateField.stringToTime(timestamp));
doc.add(timestampField);
To perform range querying or filtering against a NumericField, use
NumericRangeQuery or NumericRangeFilter. you can see the
http://wiki.apache.org/lucene-java/SearchNumericalFields to find any useful
information.

Re: about some seacher(I'm new hand, thank you for help)
Posted by sam <ha...@yahoo.com.cn>.
but,how can i used it in lucene
File logFile= new File("D:\\logFile");
BufferedReader reader=null;
String str = null;
reader = new BufferedReader(new FileReader(logFile));
while ((str=reader.readLine())!=null) {
String timestamp = str.substring(1, 13);
String content = str.substring(14).trim();
}
in this way ,we can get the data,but
document.add(new Field("content",
content,Field.Store.YES,Field.Index.NOT_ANALYZED_NO_NORMS);
it's must be wrong.

You don't know how to split the string containing the data you want to index??
String s = "2012-07-06 11:11:43 some message";
String timestamp = s.substring(0, 19);
String content = s.substring(19).trim();
is one way.

Split the data into 2 fields, timestamp and content. Store one lucene
document per line with the 2 fields, timestamp stored and not indexed
(unless you want to search on it), content stored and analyzed. Use
StandardAnalyzer unless you have special requirements.
Then close the IndexWriter, open a searcher, use QueryParser to get a
query for "content: some message", search, get and display the
timestamp and content fields and you're done.
Googling "lucene tutorial" or "lucene getting started" will get hits.
Or look at the sample/demo code at
http://lucene.apache.org/core/quickstart.html. Or, best of all, get
hold of a copy of Lucene In Action 2nd. edition.
Or take a look at Solr.
