[in] A bitmask of flags that controls the type of the passed-in strings. The following flag can be set:
The passed-in strings are in Unicode format. If the MAPI_UNICODE flag is not set, the strings are in ANSI format.
[out] A pointer to a pointer to an SRestriction structure that defines the search criteria. If a client application passes NULL in the lppRestriction parameter, GetSearchCriteria does not return an SRestriction structure.
[out] A pointer to a pointer to an array of entry identifiers that represent containers to be included in the search. If a client passes NULL in the lppContainerList parameter, GetSearchCriteria does not return an array of entry identifiers.
[out] A pointer to a bitmask of flags used to indicate the current state of the search. If a client passes NULL in the lpulSearchState parameter, GetSearchCriteria returns no flags. The following flags can be set:
The search should run at high priority relative to other searches. If this flag is not set, the search runs at normal priority relative to other searches.
The search is in the CPU-intensive mode of its operation, trying to locate messages that match the criteria. If this flag is not set, the CPU-intensive part of the search's operation is over. This flag has meaning only if the search is active (that is, if the SEARCH_RUNNING flag is set).
The search is looking in specified containers and all their child containers for matching entries. If this flag is not set, only the containers explicitly included in the last call to the IMAPIContainer::SetSearchCriteria method are being searched.
The search is active and the container's contents table is being updated to reflect changes in the message store or address book. If this flag is not set, the search is inactive and the contents table is static.
The IMAPIContainer::GetSearchCriteria method obtains the search criteria for a container that supports searches, typically a search-results folder. You create search criteria by calling a container's IMAPIContainer::SetSearchCriteria method.
Address book containers may need to support GetSearchCriteria only if they provide the advanced search capabilities associated with the PR_SEARCH (PidTagSearch) property. For more information about how to implement the advanced search feature for address book containers, see Implementing Advanced Searching.
