Method Detail

getRoots

public static org.elasticsearch.index.query.QueryBuilder getRoots(java.lang.String field,
                                                                  java.util.Collection<java.lang.String> roots)

Parameters:: field - String; roots - Set of String
Returns:: the filter associated with the roots

addRoots

public static void addRoots(org.elasticsearch.index.query.BoolQueryBuilder query,
                            java.lang.String field,
                            java.util.Collection<java.lang.String> roots,
                            int depth)

Parameters:: query -; field - String; roots - Set of String

getFullCommand

public static org.elasticsearch.index.query.QueryBuilder getFullCommand(org.elasticsearch.index.query.QueryBuilder command,
                                                                        org.elasticsearch.index.query.QueryBuilder roots)

Merge a request and a root filter

Parameters:: command - QueryBuilder; roots - QueryBuilder
Returns:: the complete request

getSorts

public static java.util.List<org.elasticsearch.search.sort.SortBuilder<?>> getSorts(AbstractParser<?> requestParser,
                                                                                    boolean score,

Generate sort list from order by ES query orders : {field1 : -1, field2 : 1} or [{field1 : -1, field2 : 1},{field3 : -1}]

Note : if the query contains a match and the collection allows to use score, the socre is added to the sort

Parameters:: requestParser - the original parser; score - True will add score first; parserTokens -
Returns:: list of order by as sort objects

Parameters:: query - Query; parserTokens -
Returns:: the associated QueryBuilder
Throws:: InvalidParseOperationException - if query could not parse to command
