fromLuceneFilter

fromLuceneSortField

public static io.searchbox.core.search.sort.Sort fromLuceneSortField(SortField sortField)

Convert a Lucene SortField to an Elasticsearch Sort, trying to preserve the exact same meaning as the SortField would have in Lucene.

For instance, missing values on numeric fields are implicitly 0 in Lucene, so this method will add it explicitly on any numeric Elasticsearch sort.

Parameters:

sortField - The Lucene SortField to convert

Returns:

The equivalent Elasticsearch Sort
