Remarks
This class imports records from any IndexableSource, represented by an IndexableSourceRecord. An IndexableSource can be
a source of data such as;
The Import method can be used to either, import a new set of documents, or to update an existing set. For example, Import
can be used first to import a web-site (which will be crawled). When it does this it saves the IndexableSourceRecord into the
index. The IndexableSourceRecord can be passed to Import later and will cause the method to update the source (adding new
documents and removing now missing documents).
- Web-site - WebSiteBasedSourceRecord
- MSSQL, Oracle, or OLE database - DatabaseBasedIndexableSourceRecord
- File-system directory - FileSystemFolderBasedSourceRecord
- Custom DataSet - CustomDataSetBasedIndexableSourceRecord
