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.

Thanks again for your help.

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
