We are delighted to announce the monthly release of GroupDocs.Search for .NET 18.12. Using the latest version, you can now index and search blended characters and perform a wildcard search. We would recommend you to install and use the latest version of the API.

Features

Following are the new features introduced in the latest version:

Blended Characters SearchGroupDocs.Search for .NET API 18.12 introduces a new class of characters - blended. When indexing, blended characters are interpreted simultaneously as valid letters and as separators. For example, if the hyphen is marked as a blended character then indexing of term ‘silver-gray’ will result in saving of 3 terms in the index: ‘silver’, ‘gray’, and ‘silver-gray’. The following code snippet shows how to work with blended characters:```

string indexFolder = @“c:\MyIndex”; string documentFolder = @“c:\MyDocuments”;

// Creating index Index index = new Index(indexFolder);

// Marking hyphen as blended character index.Dictionaries.Alphabet.SetRange(new char[] { ‘-’ }, CharacterType.Blended);

// Adding documents to index index.AddToIndex(documentFolder);

// Searching for word ‘silver-gray’ SearchResults results = index.Search(“silver-gray”);


## Wildcard SearchThe latest version allows performing search of words containing wildcards. There are two possible forms of wildcards to use in wildcard search:

*   ? - question mark representing one arbitrary character
*   ?(N~M) - the range of arbitrary characters in an amount from N to M, where N and M must be in the range from 0 to 255

This following code snippet shows how to perform wildcard search:```
 string indexFolder = @"c:\MyIndex";
string documentFolder = @"c:\MyDocuments";
   
// Creating index
Index index = new Index(indexFolder);
   
// Adding documents to index
index.AddToIndex(documentFolder);
   
// Searching for words 'affect' or 'effect' in a one document with 
// 'principal', 'principle', 'principles', or 'principally'
SearchResults results1 = index.Search("?ffect & princip?(2~4)");
   
// Searching with a single query for phrases 'assure equal opportunities', 
// 'ensure equal opportunities', and 'sure equal opportunities'
SearchResults results2 = index.Search("\"?(0~2)sure equal opportunities\"");
