Hi,
We have a need to allow each user to 'exclude' individual documents in the
results. We can easily do this now within the RDBMS using a FTS index and a
query with 'OUTER LEFT JOIN WHERE NULL' type of thing.
Can Elasticsearch do this somehow? Heavy customization is not a problem - I
would bet this has already been done. I would like to avoid multiple trips
back and forth from either the DB or Elasticsearch if possible.
Thanks!

Could you filter your query with a "not filter" based on ids?
[http://www.elasticsearch.org/guide/reference/query-dsl/not-filter.html](http://www.elasticsearch.org/guide/reference/query-dsl/not-filter.html)
[http://www.elasticsearch.org/guide/reference/query-dsl/ids-filter.html](http://www.elasticsearch.org/guide/reference/query-dsl/ids-filter.html)
Does it help?
