Total time of a search

[Lourival Júnior <ju...@gmail.com>]

Hi,

Somebody knows how to calculate the total time of a search? Actually a use
this, but I'm not sure about it:

Date d = new Date();
int iniTime = (int) d.getTime();//pega o tempo de inicio da execução da
busca nos índices

//Aqui é executada a busca nos índices.
try{
    hits = bean.search(query, start + hitsToRetrieve, hitsPerSite, "site",
sort, reverse);
} catch (IOException e){
    hits = new Hits(0,new Hit[0]);
}


int end = (int)Math.min(hits.getLength(), start + hitsPerPage);
int length = end-start;
int realEnd = (int)Math.min(hits.getLength(), start + hitsToRetrieve);


Hit[] show = hits.getHits(start, realEnd-start);
HitDetails[] details = bean.getDetails(show);
String[] summaries = bean.getSummary(details, query);

Date d2 = new Date();
int endTime = (int) d2.getTime();
int totalTime = endTime-iniTime;//tempo de execução em milisegundos
double totalTimeInSec = (double)totalTime/(double)1000;

Is it correct?

Hy,

I use the following code to measure it in millisecs:

  // Stoppuhr
  class Stoppuhr {
	long millis;
	void starte()
		{ millis = System.currentTimeMillis(); }
	
	void stoppe()
		{ millis = System.currentTimeMillis() - millis; }
	
	long lies()

	{ return millis; }
  }


  // START STOPUHR
  Stoppuhr t = new Stoppuhr();
  t.starte();

..... SEARCH

<% t.stoppe(); out.println(t.lies()/1000.000 + " sec"); %>
