                            BigArrays bigArrays,
                            ScriptService scriptService)

Method Detail

optimizeSingleShard

public boolean optimizeSingleShard()

aggregateDfs

public AggregatedDfs aggregateDfs(AtomicArray<DfsSearchResult> results)

sortDocs

public org.apache.lucene.search.ScoreDoc[] sortDocs(boolean ignoreFrom,
                                           AtomicArray<? extends QuerySearchResultProvider> resultsArr)
                                             throws IOException

Parameters:

ignoreFrom - Whether to ignore the from and sort all hits in each shard result. Enabled only for scroll search, because that only retrieves hits of length 'size' in the query phase.

resultsArr - Shard result holder

Throws:

IOException
