Delete indexed paths

GroupDocs.Search supports the ability to remove indexed files and folders from an index. Only files or folders that were explicitly added to the index can be deleted. It is not possible to remove a file or folder from the index that is a child of the indexed folder. To delete files and folders inside indexed paths, use the document filter (see Document filtering during indexing). To get a list of indexed paths, use the getIndexedPaths method of the Index class.

The following example shows how to remove indexed paths from an index.

String indexFolder = "c:\\MyIndex\\";
String documentsFolder1 = "c:\\MyDocuments\\";
String documentsFolder2 = "c:\\MyDocuments2\\";
// Creating an index in the specified folder
Index index = new Index(indexFolder);
// Indexing documents from the specified folders
// Getting indexed paths from the index
String[] indexedPaths1 = index.getIndexedPaths();
// Writing indexed paths to the console
System.out.println("Indexed paths:");
for (String path : indexedPaths1) {
    System.out.println("\t" + path);
// Deleting indexed path from the index
DeleteResult deleteResult = index.delete(new String[] { documentsFolder1 }, new UpdateOptions());
// Getting indexed paths after deletion
String[] indexedPaths2 = index.getIndexedPaths();
System.out.println("\nDeleted paths: " + deleteResult.getSuccessCount());
System.out.println("\nIndexed paths:");
for (String path : indexedPaths2) {
    System.out.println("\t" + path);
