How to use the quick text search API to search the result in my plugin about eclipse-integration-commons HOT 3 CLOSED

I had used the below code to search the result from your code ,but It cannot search the result firstly the "contentProvider" object is empty,but if you invoked these code secondly ,it will get the search result .it's very strange .

QuickTextQuery newFilter = createFilter();
System.out.println("search content is:"+newFilter);
if (this.searcher==null) {
if (!newFilter.isTrivial()) {
searcher = new QuickTextSearcher(newFilter, context.createPriorityFun(), new QuickTextSearchRequestor(){
@OverRide
public void add(LineItem match) {
System.out.println("QuickTextSearchRequestor add function..."+contentProvider.getNumberOfElements());
contentProvider.add(match);
smallProvider.add(match);
myitem.add(match);
contentProvider.refresh();
}

                        @Override
                        public void clear() {
                            System.out.println("QuickTextSearchRequestor clear function...");
                            contentProvider.reset();
                            contentProvider.refresh();
                        }
                        @Override
                        public void revoke(LineItem match) {
                             System.out.println("QuickTextSearchRequestor revoke function...");
                             contentProvider.remove(match);
                             contentProvider.refresh();
                        }
                        @Override
                        public void update(LineItem match) {
                            contentProvider.refresh();
                        }
                  });


         }
      }else {
            //The QuickTextSearcher is already active update the query
            this.searcher.setQuery(newFilter);
       }

       if (progressJob!=null) {
            progressJob.schedule();
        } 
     System.out.println("content find is:"+contentProvider.getNumberOfElements()+",content are :\n"+contentProvider.items.toString());

The quick text searcher is 'asynchronous' and adds and removes results to
the search requestor over time. There never is a final 'result'.
The responsibility of the SearchRequestor is to update the evolving results
in the UI as they arrive or get revoked.
So you can not perform a search and get 'the result'.

I think your test code launches a search and then immediately prints the
number of results once.
So it really only prints the few results that have already been found in
the few milliseconds since the
result got started. The search is still running and would find more results
later if you let it.

If you want to have a more meaningful test, you should keep the quickserach
object alive (i.e. not call
'cancel' on it and print the number of results in your contentProvider each
time it changes
(i.e. each time 'add', 'update', 'revoke' or 'clear' is called on the
requestor.)

You should see more results getting added over time.

If you change the query the live results will be updated (i.e. depending on
the query change
either the results will be cleared completely and search restarted, or the
search keeps going
and some already found elements are selectively 'revoked'.

thanks very much for your support .i had researched your code and now implement in my plugin .
it's really very awesome with 'asynchronous" status to check the result ....

thanks for your guys .i will under your plugin license for my plugin ...
