Indexing metadata of documents Leave feedback

GroupDocs.Search allows creating a full-text index or a metadata index of documents. To index only metadata without the main content of documents, set the IndexType property of the index settings to IndexType.MetadataIndex when creating an index. The size of an index of this type will be very small. The index type is fixed when the index is created, so it cannot be changed for an existing index.

The following example demonstrates the creation of the metadata index.

C#

string indexFolder = @"c:\MyIndex\";
string documentsFolder = @"c:\MyDocuments\";
 
// Creating an instance of index settings
IndexSettings settings = new IndexSettings();
settings.IndexType = IndexType.MetadataIndex; // Setting index type
 
// Creating a new index in the specified folder
Index index = new Index(indexFolder, settings, true);
 
// Indexing documents from the specified folder
index.Add(documentsFolder);
 
// Searching in the index
SearchResult result = index.Search("Einstein");
