Migration Notes Leave feedback
Here are the main reasons for using the new updated API provided by GroupDocs.Search for .NET from version 19.9:
- Unified work with some similar entities to increase the intuitiveness of using API.
- The architecture of the product has been revised and optimized, so that some functions will work faster.
- Some entities have been renamed to improve code readability.
- The changes made to the API are not too significant, so the migration will not be too difficult.
- New functionality will not be added to the old API version, only to the new version.
The following code examples demonstrate changes in the use of the API.
Old coding style:
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.AddToIndex(documentsFolder);
// Creating a search parameters object
SearchParameters parameters = new SearchParameters();
parameters.FuzzySearch.Enabled = true; // Enabling the fuzzy search
parameters.FuzzySearch.FuzzyAlgorithm = new TableDiscreteFunction(2); // Setting the number of possible differences for each word
// Searching in the index
SearchResults results = index.Search("Happiness", parameters);
if (results.Count > 0)
{
// Generating HTML-formatted text of a document with highlighted search results
index.HighlightInText(@"c:\Highlighted.html", results[0]);
}
New coding style:
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);
// Creating a search options object
SearchOptions options = new SearchOptions();
options.FuzzySearch.Enabled = true; // Enabling the fuzzy search
options.FuzzySearch.FuzzyAlgorithm = new TableDiscreteFunction(2); // Setting the number of possible differences for each word
// Searching in the index
SearchResult result = index.Search("Happiness", options);
if (result.DocumentCount > 0)
{
// Generating HTML-formatted text of a document with highlighted search results
index.Highlight(result.GetFoundDocument(0), new HtmlHighlighter(new FileOutputAdapter(@"c:\Highlighted.html")));
}
