| /** |
| * Returns the list of "entity" keys possessing the keyedReferences passed in or the level below. |
| * For findBusiness queries, this means keyedReferences on the businessEntity and service levels, |
| * and for findService queries this means keyedReferences on the service and serviceBinding level. |
| * |
| * Output is restricted by list of "entity" keys passed in. If null, all entities are searched. |
| * Output is produced by building the appropriate JPA query based on input and find qualifiers. |
| * |
| * From the spec : |
| * |
| * * From specification: |
| * "combineCategoryBags: this may only be used in the find_business and find_service calls. In the case of |
| * find_business, this qualifier makes the categoryBag entries for the full businessEntity element behave as though all |
| * categoryBag elements found at the businessEntity level and in all contained or referenced businessService elements |
| * and bindingTemplate elements were combined. Searching for a category will yield a positive match on a registered |
| * business if any of the categoryBag elements contained within the full businessEntity element (including the |
| * categoryBag elements within contained or referenced businessService elements or bindingTemplate elements) |
| * contains the filter criteria. In the case of find_service, this qualifier makes the categoryBag entries |
| * for the full businessService element behave as though all categoryBag elements found at the businessService level |
| * and in all contained or referenced elements in the bindingTemplate elements were combined. Searching for a category |
| * will yield a positive match on a registered service if any of the categoryBag elements contained within the |
| * full businessService element (including the categoryBag elements within contained or referenced bindingTemplate |
| * elements) contains the filter criteria. This find qualifier does not cause the keyedReferences in categoryBags |
| * to be combined with the keyedReferences in keyedReferenceGroups in categoryBags when performing the comparison. |
| * The keyedReferences are combined with each other, and the keyedReferenceGroups are combined with each other." |
| * |
| * |
| * NOTES: |
| * 1) Categories are grouped with a logical AND by default. |
| * 2) Concerning when the categories are AND'd together - the only way this can be done with a single query was to create a self-join for |
| * each category. If there are a lot of categories, the performance could suffer. |
| * TODO: Test performance with multiple AND'd categories. If too slow, look to process this query in multiple steps. |
| * 3) The "orLikeKeys" qualifier complicates matters. The "like" keys are OR'd together and these groups of "like" keys are AND'd together. |
| * As with "andAllKeys", self-joins are created but only one for each group of "like" keys. If none of the keyedReferences passed are alike then this |
| * will reduce to an "andAllKeys" query. If all are alike, then this will query will exhibit the behavior of OR'ing all keys. |
