getStringSortField

@Deprecated
public static org.apache.lucene.search.SortField getStringSortField(String fieldName,
                                                                    boolean reverse,

Deprecated.

custom FieldTypes should use FieldType.getSortField(org.apache.solr.schema.SchemaField, boolean). Other usage should leverage th underling lucene SortField classes directly.

Returns a SortField for a string field. If nullLast and nullFirst are both false, then default lucene string sorting is used where null strings sort first in an ascending sort, and last in a descending sort.

Parameters:

fieldName - the name of the field to sort on

reverse - true for a reverse (desc) sort

nullLast - true if null should come last, regardless of sort order

nullFirst - true if null should come first, regardless of sort order

Returns:

SortField

getTextSortField

public static org.apache.lucene.search.SortField getTextSortField(String fieldName,
                                                                  boolean reverse,
                                                                  boolean nullLast,
                                                                  boolean nullFirst)

Deprecated.

custom FieldTypes should use FieldType.getSortedSetSortField(org.apache.solr.schema.SchemaField, org.apache.lucene.search.SortedSetSelector.Type, boolean, java.lang.Object, java.lang.Object). Other usage should leverage th underling lucene SortedSetSortField classes directly.

Like getStringSortField(java.lang.String, boolean, boolean, boolean)) except safe for tokenized fields
