Using aliases Leave feedback

The use of aliases allows you to reduce the length of search queries in text form. To use an alias in a search query, you must enter the @ symbol with the name of the alias after it without spaces.

Aliases are stored in the alias dictionary. By default the alias dictionary is empty. Detailed information on managing the alias dictionary can be found on the Alias dictionary page of the Managing dictionaries section.

An example of using aliases for searching is presented below.

C#

string indexFolder = @"c:\MyIndex\";
string documentsFolder = @"c:\MyDocuments\";
 
// Creating an index in the specified folder
Index index = new Index(indexFolder);
 
// Indexing documents from the specified folder
index.Add(documentsFolder);
 
// Adding aliases to the alias dictionary
index.Dictionaries.AliasDictionary.Add("t", "(theory OR relativity)");
index.Dictionaries.AliasDictionary.Add("e", "(Einstein OR Albert)");
 
// Search in the index
SearchResult result = index.Search("@t OR @e");
