| ISearchPersistentItemsChangedSink Provides methods for passing change notifications to alert the indexer that items need to be updated. |
| ISearchProtocol Provides methods for invoking, initializing, and managing IUrlAccessor objects. (ISearchProtocol) |
| ISearchProtocol2 Provides methods for invoking, initializing, and managing IUrlAccessor objects. (ISearchProtocol2) |
| ISearchProtocolThreadContext This optional interface enables the protocol handler to perform an action on the thread used for filtering in the protocol host. |
| ISearchQueryHelper Provides methods for building a query from user input, converting a query to Windows Search SQL, and obtaining a connection string to initialize a connection to the Window Search index. |
| ISearchRoot Provides methods for manipulating a search root. Changes to property members are applied to any URL that falls under the search root. A URL falls under a search root if it matches the search root URL or is a hierarchical child of that URL. |
| ISearchScopeRule Provides methods to define scope rules for crawling and indexing. |
| ISearchViewChangedSink Not implemented. (ISearchViewChangedSink) |
| ISimpleCommandCreator Contains methods for interacting with the file catalog. |
| IStemmer Provides methods for creating a language-specific stemmer. The stemmer generates inflected forms of a specified word. |
| ITokenCollection Gets the tokens that result from using a word breaker. |
| IUrlAccessor Provides methods for processing an individual item in a content source whose URL is provided by the gatherer to the filter host. |
| IUrlAccessor2 Extends functionality of the IUrlAccessor interface. |
| IUrlAccessor3 Extends the functionality of the IUrlAccessor2 interface with the IUrlAccessor3::GetImpersonationSidBlobs method to identify user security identifiers (SIDs) for a specified URL. |
| IUrlAccessor4 Extends the functionality of the IUrlAccessor3 interface with the IUrlAccessor4::ShouldIndexItemContent method that identifies whether the content of the item should be indexed. |
| IWordBreaker Parses text and identifies individual words and phrases. This interface is a language-specific language resource component. It is used in background processes and must be optimized for both throughput and minimal use of resources. |
| IWordFormSink Handles the list of alternative word forms that stemmers generate during query time. |
Structures
| AUTHENTICATION_INFO Describes security authentication information for content access. |
| FILTERED_DATA_SOURCES Specifies parameters for a Shell data source for which a filter is loaded. |
| HITRANGE Identifies the range of matching data when query search conditions match indexed data. |
| INCREMENTAL_ACCESS_INFO Contains access information used by an incremental crawl, such as the last access date and modification time. |
| ITEM_INFO Contains information passed to the IUrlAccessor object about the current item; for example, the application name and catalog name. |
| ITEMPROP Stores information about properties in the Windows Property System, and is used by the IItemPropertyBag interface. |
| PROXY_INFO Stores information about a proxy. Used by ISearchProtocol. |
| SEARCH_COLUMN_PROPERTIES This structure is not implemented. |
| SEARCH_ITEM_CHANGE Specifies the changes to an indexed item. |
| SEARCH_ITEM_INDEXING_STATUS Describes the status of a document to be indexed. |
| SEARCH_ITEM_PERSISTENT_CHANGE Contains information about the kind of change that has occurred in an item to be indexed. This structure is used with the ISearchPersistentItemsChangedSink::OnItemsChanged method to pass information to the indexer about what has changed. |
| TEXT_SOURCE Contains information about text that the word breaker will process. |
| TIMEOUT_INFO Stores time-out values for connections and data. |
