Integrate Dynabic.Metered to GroupDocs.Search

This enhancement allows using Dynabic.Metered account to run library in licensed mode. It works only with the enabled internet connection.

Public API Changes
Class Metered has been added to GroupDocs.Search namespace.

This example demonstrates how to use the library in the licensed mode using Dynabic.Metered account:

C#

const string publicKey = "[Your Dynabic.Metered public key]";
const string privateKey = "[Your Dynabic.Metered private key]";

// initialize Metered API and set-up credentials
new Metered().SetMeteredKey(publicKey, privateKey);

// do indexing and searching in licensed mode 

Implement dictionary of letters

This feature allows managing list of searchable letters. Letters that are not in the dictionary considered as separators.

Users can change the list of searchable letters before indexing.

Dictionary of letters contains default collection of characters: digits, Latin and Cyrillic.

Public API Changes
Class Alphabet has been added to GroupDocs.Search namespace.
Property **GroupDocs.Search.**Alphabet Alphabet has been added to GroupDocs.Search.DictionaryCollection class.

This example shows how to manage dictionary of letters:

C#

string indexFolder = @"c:\MyIndex";
string documentsFolder = @"c:\MyDocuments";
string alphabetFileName = @"c:\MyAlphabet.txt";

Index index = new Index(indexFolder);

// Clearing dictionary of letters
index.Dictionaries.Alphabet.Clear();

// Adding letters
char[] letters = new char[] { '\u0141', '\u0142', '\u0143', '\u0144' };
index.Dictionaries.Alphabet.AddRange(letters);

// Import alphabet from file. Existing letters are staying.
index.Dictionaries.Alphabet.Import(alphabetFileName);
// Export alphabet to file
index.Dictionaries.Alphabet.Export(@"c:\MyExportedAlphabet.txt");

// Indexing
index.AddToIndex(documentsFolder);
