IndexJob provides two ways to specify the text to be indexed: the ToAddXXX members let you specify directories and filename filters identifying a set of disk files to index, and the DataSourceToIndex member lets you supply text data directly to the dtSearch Engine for indexing. When using the multithreaded DataSource API, the indexer will index all documents returned from GetNextDoc even if they have not changed since the last time they were indexed, so to prevent redundant indexing, the indexing application should only return new or modified documents from the DataSource. The index's alphabet and noise word list are initialized and cannot be changed without deleting the index. If more than one index path is provided, separate the paths with spaces.

The dataSourceToIndex property provides a way to supply text to be indexed to the dtSearch Engine when the text is not accessible as a disk file. There are two ways to remove documents from an index: (1) You can set the "Remove Deleted" flag in an index job, which indicates that each file in the index should be checked and, if the corresponding disk file does not exist, the file is to be removed from the index. To receive callbacks during a search with the name of each document as it is found, create an object that implements the ISearchStatusHandler interface and attach it to the SearchJob's StatusHandler.
