Method Detail

resolve

public static StaticProductSet[] resolve(ProductSet[] productSets,
                                         Searcher searcher,
                                         SearchContext searchContext)

Resolve the given product sets into static product sets. For given static product sets, the specified IDs are verified. For dynamic product sets, the matching IDs are fetched.

Parameters:

productSets -

searcher -

searchContext -

Returns:

extendQuery

public static void extendQuery(MasterVariantQuery searchQuery,
                               InternalSearchParams internalParams)

Extend MasterVariantQuery to inject the hero products and boost them to the top.

Parameters:

searchQuery -

internalParams -

getCorrectedMinHitCount

public static int getCorrectedMinHitCount(InternalSearchParams internalParams)

Get minimum hitCount to accept the natural search to have matched anything. This is necessary to follow the query-relaxation chain until we have the original result, as if there wouldn't be any hero products.

Parameters:

internalParams -

Returns:

the expected minimum hit count

extractSlices

public static int extractSlices(org.elasticsearch.action.search.SearchResponse searchResponse,
                                InternalSearchParams internalParams,
                                SearchResult searchResult)

Extract the hero products into separate ordered slices, that are attached to the searchResult.

In case the result was sorted or filtered, this method most likely won't extract slices anymore, because it expects them in the defined order at the top of the result.

Parameters:

searchResponse -

internalParams -

searchResult -

Returns:

fetchOffset: the index of the first hit, that is not a hero product
