Constructor Detail

FacetSearchParams

public FacetSearchParams(FacetIndexingParams indexingParams)

Construct with specific faceted indexing parameters. It is important to know the indexing parameters so as to e.g. read facets data correctly from the index. addFacetRequest(FacetRequest) must be called at least once for this faceted search to find any faceted result.

Parameters:

indexingParams - Indexing faceted parameters which were used at indexing time.

addFacetRequest(FacetRequest)

FacetSearchParams

public FacetSearchParams()

Construct with default faceted indexing parameters. Usage of this constructor is valid only if also during indexing the default faceted indexing parameters were used. addFacetRequest(FacetRequest) must be called at least once for this faceted search to find any faceted result.

See Also:

addFacetRequest(FacetRequest)

Method Detail

getFacetIndexingParams

public final FacetIndexingParams getFacetIndexingParams()

A list of FacetRequest objects, determining what to count. If the returned collection is empty, the faceted search will return no facet results!

getFacetRequests

public final List<FacetRequest> getFacetRequests()

Parameters which controlled the indexing of facets, and which are also needed during search.

addFacetRequest

public void addFacetRequest(FacetRequest facetRequest)

Add a facet request to apply for this faceted search. This method must be called at least once for faceted search to find any faceted result.
NOTE: The order of addition implies the order of the FacetResults

Parameters:

facetRequest - facet request to be added.

toString

public String toString()

Overrides:

toString in class Object

getClCache

public CategoryListCache getClCache()

Returns:

the cldCache in effect

setClCache

public void setClCache(CategoryListCache clCache)

Set Cached Category Lists data to be used in Faceted search.

Parameters:

clCache - the cldCache to set
