Method Detail

search

public <T> SearchPageData<T> search(PaginatedFlexibleSearchParameter parameter)

Description copied from interface: PaginatedFlexibleSearchService

Searches according to PaginatedFlexibleSearchParameter.

Specified by:

search in interface PaginatedFlexibleSearchService

Type Parameters:

T - The type of item returned from the search

Parameters:

parameter - A parameter object containing all attributes needed for paginated flexible search. The sort info should be only populated in PaginatedFlexibleSearchParameter.searchPageData

• PaginatedFlexibleSearchParameter.flexibleSearchQuery - The flexible search query containing String query and flexible search query parameters as Map<String, Object>
• PaginatedFlexibleSearchParameter.searchPageData - The search page data containing requested pagination and sort data
• PaginatedFlexibleSearchParameter.sortCodeToQueryAlias - The map between sort code and query alias which will be used to dynamically generate "ORDER BY" clause by appending to the given flexible search query based on requested sorts.

Returns:

an instance of SearchPageData containing the search results with applied sorts and pagination data

validatePaginatedFlexibleSearchParameter

protected void validatePaginatedFlexibleSearchParameter(PaginatedFlexibleSearchParameter parameter)

Validates if the given PaginatedFlexibleSearchParameter contains valid parameters.

Parameters:

parameter - the PaginatedFlexibleSearchParameter

Throws:

java.lang.IllegalArgumentException - if parameter contains invalid data

populateSearchQuery

protected FlexibleSearchQuery populateSearchQuery(SearchPageData searchPageData,
                                                  FlexibleSearchQuery searchQuery,
                                                  java.util.Map<java.lang.String,java.lang.String> sortCodeToQueryAlias,
                                                  boolean nextElementAdded)

Populates a FlexibleSearchQuery based on given searchQuery by appending "ORDER BY" clause if given searchPageData has list of SortData.

Parameters:

searchPageData - the searchPageData contains requested pagination and sorting information

searchQuery - the searchQuery

sortCodeToQueryAlias - the sortCodeToQueryAlias contains mapping between sort code and query alias which will be used to dynamically generate "ORDER BY" clause.

nextElementAdded -

Returns:

the FlexibleSearchQuery with requested sorts applied

filterSearchPageDataSorts

protected java.util.List<SortData> filterSearchPageDataSorts(SearchPageData searchPageData,
                                                             java.util.Map<java.lang.String,java.lang.String> sortCodeToQueryAlias)

Returns a list of SortData where each of it exists from given sortCodeToQueryAlias map. The intention of method is to filter out the undefined sort code from given SearchPageData.getSorts() based on given sortCodeToQueryAlias map, so that once buildSortsAppliedQuery(String, SearchPageData, Map) is called, sortDataParsingStrategy is guaranteed to return the mapped query alias for each sort code.

It also converts sortData's code to lower case to meet the expectation of SortDataParsingStrategy

Parameters:

searchPageData - the searchPageData contains list of SortData which will be used as requested sort list

sortCodeToQueryAlias - the sortCodeToQueryAlias contains mapping between sort code and query alias which will be used to generate "ORDER BY" clause dynamically based on requested sort codes

Returns:

the list of SortData where each of them found from given sortCodeToQueryAlias

SortDataParsingStrategy

buildSortsAppliedQuery

protected java.lang.String buildSortsAppliedQuery(java.lang.String query,
                                                  SearchPageData searchPageData,
                                                  java.util.Map<java.lang.String,java.lang.String> sortCodeToQueryAlias)

Builds a requested sorts applied query based on given query by appending list of SortData passed from given searchPageData. It uses SortDataParsingStrategy to properly generate "ORDER BY {queryAlias:sortCode} asc|desc" search query dynamically based on the requested sorts. If the list of SortData from given searchPageData is empty, the given query will be returned without any modification.

Parameters:

query - the query

searchPageData - the searchPageData contains requested pagination and sorting information

sortCodeToQueryAlias - the sortCodeToQueryAlias contains mapping between sort code and query alias which will be used to generate "ORDER BY" clause dynamically based on requested sort codes

Returns:

a requested sorts applied query

createPagedSearchResult

protected <T> SearchPageData<T> createPagedSearchResult(SearchResult<T> searchResult,
                                                        SearchPageData searchPageData,
                                                        DefaultPaginatedFlexibleSearchService.SearchResultInfo searchResultInfo)

Returns an instance of {link SearchPageData} with given SearchResult. It also contains updated pagination and applied sorts information

Type Parameters:

T - the type of item returned from the search

Parameters:

searchResult - the searchResult

searchPageData - the searchPageData containing pagination and sorting information

searchResultInfo - the search result info needed to properly calculate slicing (hasNext, hasPrevious values)

Returns:

an instance of SearchPageData with searchResult, pagination and sorting information

createPagination

protected <T> PaginationData createPagination(SearchPageData searchPageDataInput,
                                              DefaultPaginatedFlexibleSearchService.SearchResultInfo searchResultInfo)

Creates PaginationData based on searchPageDataInput.pagination and calculates the numberOfPages based on the totalNumberOfResults.

Type Parameters:

T - the type of item returned from the search

Parameters:

searchPageDataInput - the searchPageDataInput contains pagination and sorting information

searchResultInfo - the search result info needed to properly calculate slicing (hasNext, hasPrevious values)

Returns:
