Thanks Antony for the idea.
The only thing that may prevent it from working well is that the index
is updated frequently so the docid to ext id or cache needs to be
updated freq, which may affect the performance.
Thanks again for your help.

Thanks Sawan for the suggestion.
I guess this will work for statically known doc ids. In my case, I
know only external ids that I want to exclude from the result set.for
each search. Of course, I can always exclude these docs in a post
search process. I am curious if there are other more efficient approach.
When you open a searcher, you could create a cached array of all your
external Ids with their Lucene DocId. Using a custom HitCollector,
which can be created with the Ids you wish to exclude, you can get a
document's external Id during the collect() method using the docid.
Then just check the external Id of the matched document against the
exclusion list.
As long as you have your searcher open, the cache will remain valid.

Hello Jay,
I am not sure up to what level I understood your problem . But as far
as my
assumption, you can try HitCollector class and its collect method.
Here you
can get DocID for each hit and can remove while searching.
Hope it will be useful.

Hi everyone,
I am trying to remove several docs from search results each time I do
query. The docs can be identified by an exteranl ids whcih are
saved/indexed. I could use a Query or QueryFilter to achieve this but
not sure if it's the most efficient way to do that.
Anyone has any experience or idea?
Thanks!
Jay
