queue and not from virtual documents generated by the parser.
- The parser now generates nice description texts for NOLOAD entries
which shall make it possible to find media content using the search
index and not using the media prefetch algorithm during search (which
was costly)
- Removed the media-search prefetch process from image search
only links where the content can be parsed. All non-parseable links are
placed into the noload queue. The search process must therefore be able
to filter out non-text search results.
- This fixes the problem that image search results appeared in the text
search.
- The interactive search can retrieve now ALL types of links
- The p2p interface is now extended to retrieve only certain types of
links (text, image, video, apps)
- The search process has an extension to filter the right document type
according to the search query
check semantically wrong, but a trick that prevented an IP lookup in
case that the filter was not used did not work. That bugfix causes that
crawling gets a huge speed boost for noload urls!
See
http://docs.oracle.com/javase/6/docs/api/java/util/concurrent/ConcurrentLinkedQueue.html
and the following test programm:
public class QueueLengthTimeTest {
public static long countTest(Queue<Integer> q, int c) {
long t = System.currentTimeMillis();
for (int i = 0; i < c; i++) {
q.add(q.size());
}
return System.currentTimeMillis() - t;
}
public static void main(String[] args) {
int c = 1;
for (int i = 0; i < 100; i++) {
Runtime.getRuntime().gc();
long t1 = countTest(new ArrayBlockingQueue<Integer>(c), c);
Runtime.getRuntime().gc();
long t2 = countTest(new LinkedBlockingQueue<Integer>(), c);
Runtime.getRuntime().gc();
long t3 = countTest(new ConcurrentLinkedQueue<Integer>(),
c);
System.out.println("count = " + c + ": ArrayBlockingQueue =
" + t1 + ", LinkedBlockingQueue = " + t2 + ", ConcurrentLinkedQueue = "
+ t3);
c = c * 2;
}
}
}
ready-prepared crawl list but at the stacks of the domains that are
stored for balanced crawling. This affects also the balancer since that
does not need to prepare the pre-selected crawl list for monitoring. As
a effect:
- it is no more possible to see the correct order of next to-be-crawled
links, since that depends on the actual state of the balancer stack the
next time another url is requested for loading
- the balancer works better since the next url can be selected according
to the current situation and not according to a pre-selected order.
these bookmarks will be used to get a source reference for the search in case of intranet or portal searches.

- moved the domain cache for domain counter from the crawl switchboard to the crawl profiles. the crawl domain counter is now therefore relative for each crawl start, not for the whole crawler.
