IDD search allows a user to search records by subject area and subject area group. If a subject area has any data security filters for the user, then search results should contain only those records that meet the data security. Data security is applied for both basic and fuzzy searches. For example, when a user performs a search and has access only to people in CA, the search result displays only records of people in CA.
If a user with data security performs a search using a search term, the search result is an intersection of the records that meet data security and what is returned by the search.
If the search de-duplication for a child record is not enabled and the user with data security on the primary objects is more than one child record, then the search result will have all the records related to the primary object.
When search is performed over subject area group, different data security filters are used.
IDD collapses all duplicates in case of amount of found records is less than configured server page size, for example, all results are fetched after first request.
