Hello,
I'm using tomcat to run my servlet. This is the code of processReuqest
method:
response.setContentType("text/xml;charset=UTF-8");
PrintWriter outResponse = response.getWriter();
StringBuffer out = new StringBuffer();
try {
String search = request.getParameter("q");
// Lucene properties
String index = "/tmp/index/";
org.apache.lucene.search.BooleanQuery.setMaxClauseCount(Integer.MAX_VALUE);
IndexReader id = IndexReader.open(index);
IndexSearcher is = new IndexSearcher(id);
Analyzer analyzer = new StandardAnalyzer();
QueryParser parser = new QueryParser("all", analyzer);
Query query = parser.parse(search);
Hits hits = is.search(query);
out.append("<?xml version=\"1.0\" encoding=\"UTF-8\"?>");
out.append("<response>");
out.append("<result name=\"response\">");
long startTime =0;
long alltime = 0;
for(int i=0;i<hits.length();i++){
out.append("<doc><str name=\"id\">");
startTime = System.currentTimeMillis();
String s = hits.doc(i).get("id");
alltime += (System.currentTimeMillis() - startTime);
out.append(s);
out.append("</str></doc>");
}
System.out.println("Time: " + alltime + "ms");
out.append("</result>");
out.append("</response>");
startTime = System.currentTimeMillis();
outResponse.print(out.toString());
System.out.println(System.currentTimeMillis()-startTime);
} finally {
long startTime = System.currentTimeMillis();
outResponse.close();
System.out.println(System.currentTimeMillis()-startTime);
}
}
I'm getting documents from lucene and creating a string with all the
results with string buffer. The string creation takes 2 seconds and the
outResponse.print(out.toString());
takes 1 second. Closing the writer take no time at all, although I have
to wait 2 minutes until the result shows in firefox. The same happens
with solr, that should make something like that. The xml file, only has
300KB. Why I need to wait for so long?
Thank you.
