Searching for a period or in general by time is done by the server only if you use IMAP to connect. Example:

SearchTerm term = null;

Calendar cal = null;
cal = Calendar.getInstance();
Date minDate = new Date(cal.getTimeInMillis());  //get today date

cal.add(Calendar.DAY_OF_MONTH, 1);  //add 1 day
Date maxDate = new Date(cal.getTimeInMillis());  //get tomorrow date
ReceivedDateTerm minDateTerm = new ReceivedDateTerm(ComparisonTerm.GE, minDate);
ReceivedDateTerm maxDateTerm = new ReceivedDateTerm(ComparisonTerm.LE, maxDate);

term = new AndTerm(term, minDateTerm);  //concat the search terms
term = new AndTerm(term, maxDateTerm);

Message messages[] = folderInbox.search(term);  //search on the imap serverIf you instead of IMAP use POP3, I guess your only choice is to filter (on the client) on the entire list of messages that you fetched from the server, iterating over it, like @user2310289 was telling you:

for (int i = 0; i < arrayMessages.length; i++) {
  Message message = arrayMessages[i];
  if (message.getSentDate().after(minDate) && message.getSentDate().before(maxDate))
  {
  //do whatever you want with your filtered by period message
  }
}
