Yoann Rodière ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *updated* an issue Hibernate Search ( https://hibernate.atlassian.net/browse/HSEARCH?atlOrigin=eyJpIjoiNzMwYzk4... ) / Improvement ( https://hibernate.atlassian.net/browse/HSEARCH-2345?atlOrigin=eyJpIjoiNzM... ) HSEARCH-2345 ( https://hibernate.atlassian.net/browse/HSEARCH-2345?atlOrigin=eyJpIjoiNzM... ) Support for parallel searchers ( https://hibernate.atlassian.net/browse/HSEARCH-2345?atlOrigin=eyJpIjoiNzM... ) Change By: Yoann Rodière ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) Lucene has support to pass in an {{ExecutorService}} to the {{IndexReader}} in order to do searches in parallel across segments. Currently when sharding is used, query performance is {{O \ (n \ )}} where n is the number of IndexManagers involved. The caveat is that the {{ExecutorService}} only is used to certain methods from {{IndexReader}}, and also it is not suitable to all cases: it will trade latency for throughput, so ideally this should be configurable.
