Method Detail

doCrossSearch

public SearchResult doCrossSearch(SearchRequest searchRequest,
                                  CrossSearchTypeInfo crossSearchType)

metaFilter

private SearchResult metaFilter(SearchResult searchResult,
                                SearchRequest searchRequest)

Parameters:

searchResult -

searchRequest -

Returns:

a sorted and paginated result

mapResultRow

private SearchResultRow mapResultRow(Map<String,SearchResultRow> permutation,
                                     CrossSearchTypeInfo crossSearchType)

Maps results from multiple searches into a single result row

Parameters:

permutation -

crossSearchType -

Returns:

a mapped SearchResultRow

mapResultRow

private SearchResultRow mapResultRow(String subSearchKey,
                                     SearchResultRow row,
