Implement loading an index from disk into memory completely

This feature allows you to load a regular index from disk into memory completely, thereby speeding up its operation. Note that you must explicitly call the SaveTo method to save any changes to the index.

Public API changes

Method GroupDocs.Search.Index LoadIntoMemoryCompletely(System.String) has been added to GroupDocs.Search.Index class.
Method GroupDocs.Search.Index LoadIntoMemoryCompletely(System.String, GroupDocs.Search.IndexSettings) has been added to GroupDocs.Search.Index class.

Use cases

The following example shows how to completely load an index into memory to improve its performance.

C#

string indexFolder = @"c:\MyIndex\";
string documentsFolder = @"c:\MyDocuments\";

// Creating a regular index on disk
Index index = new Index(indexFolder);

// Indexing documents from the specified folder
index.Add(documentsFolder);

// Closing the regular index
index.Dispose();

// Loading the index entirely in memory for increased performance
Index inMemoryIndex = Index.LoadIntoMemoryCompletely(indexFolder);

// Searching in the index
string query = "focus";
SearchResult result = inMemoryIndex.Search(query);
