HTMLDocument.java example

The example code that ships with Lucene includes the following snippet in HTMLDocument.java:

    // Add the last modified date of the file a field named "modified".  Use a
    // Keyword field, so that it's searchable, but so that no attempt is made
    // to tokenize the field into words.
    doc.add(Field.Keyword("modified",
			  DateField.timeToString(f.lastModified())));

Now, I guess the point of this is so that we can search for HTML documents using Lucene's range search syntax. But as far as I can tell, the result of DateField.timeToString(f.lastModified()) returns a non-human readable date format, hence the modified field will not really be "human searchable" format. Is this an oversight in the example implementation, or am I just missing something else here?

Thanks in advance,


Simon

I always thought that this is necessary for being able to incrementally 
update the index at some later stage, but I am not sure to be honest.

Simon,

I believe there's another method in DateField that converts the value into a
human readable form.

Regards,

Terry

Now, I guess the point of this is so that we can search for HTML documents
using Lucene's range search syntax. But as far as I can tell, the result of
DateField.timeToString(f.lastModified()) returns a non-human readable date
format, hence the modified field will not really be "human searchable"
format. Is this an oversight in the example implementation, or am I just
missing something else here?
