Method Details

mapSearchHit

public static ResultHit mapSearchHit(org.elasticsearch.search.SearchHit hit,
 Map<String,org.elasticsearch.search.sort.SortOrder> sortedFields)

mapSearchHit

public static ResultHit mapSearchHit(org.elasticsearch.search.SearchHit hit,
 Map<String,org.elasticsearch.search.sort.SortOrder> sortedFields,
 VariantPickingStrategy variantPickingStrategy)

Extract a result document from the search-hit. This includes some extra logic for variant handling:

• If sortedFields are given, then documents that have several values at a sort field will get a "${fieldname}_prefix" field with the value '{from}' (for asc order) or '{to}' (for desc order). Also according to the sort order the according lowest or highest value is put into the according field.
  Example: With this behavior it is possible to show "from 10€" (for asc price sorting) or "to 59€" (for desc price sorting) for products that have several variants with different prices.
• The result-data of a variant is put into the document if one of the following conditions met:
  - the search hit only contains 1 variant
  - the first variant has a better matching score than the second variant
  - the 'preferVariantHits' flag is true

Parameters:

hit - ES search hit

sortedFields - map with field-to-sortOrder entries applicable on variant level (no validation done here)

variantPickingStrategy - function to pick variant in case of inner variant hits

Returns:

mapped result hit
