Public API and Backward Incompatible Changes

Implement the ability to separately extract data from documents in the search network

This functionality allows you to extract data from documents in the search network without indexing the extracted data. This separation of the extraction functionality allows you to create a temporary network, dedicating significant computing resources for a short period of time only to extraction. Then the computing resources for extraction can be freed up, and a smaller portion of the computing resources needed for searching the network will be used.

Public API changes

Property GroupDocs.Search.Common.ExtractedData Data has been added to GroupDocs.Search.Scaling.Events.DataExtractedEventArgs class.
Method Void Extract(System.Collections.Generic.IList<GroupDocs.Search.Common.Document>, System.Collections.Generic.IList<System.String>, GroupDocs.Search.Options.IndexingOptions) has been added to GroupDocs.Search.Scaling.Indexer class.
Property GroupDocs.Search.Scaling.SearchNetworkStatus Status has been added to GroupDocs.Search.Scaling.Indexer class.
Event System.EventHandler ExtractionCompleted has been added to GroupDocs.Search.Scaling.Events.NodeEventHub class.
Field GroupDocs.Search.Scaling.SearchNetworkStatus Extracting has been added to GroupDocs.Search.Scaling.SearchNetworkStatus enum.

Use cases

List<ExtractedData> extractedData = new List<ExtractedData>();

// Subscribing to the event to receive data extraction results
node.Events.DataExtracted += (s, e) =>
{
    extractedData.Add(e.Data);
};

Stream[] streams = new Stream[filePaths.Length];
Document[] documents = new Document[filePaths.Length];
string[] passwords = new string[filePaths.Length];
for (int i = 0; i < filePaths.Length; i++)
{
    string filePath = filePaths[i];
    DateTime modificationDate = File.GetLastWriteTime(filePath);
    string fileName = Path.GetFileName(filePath);
    string extension = Path.GetExtension(filePath);
    Stream stream = File.OpenRead(filePath);
    streams[i] = stream;
    Document document = Document.CreateFromStream(
        fileName,
        modificationDate,
        extension,
        stream);
    documents[i] = document;
}

IndexingOptions options = new IndexingOptions();
options.UseRawTextExtraction = false;
options.ImageIndexingOptions.EnabledForSeparateImages = true;
options.ImageIndexingOptions.EnabledForEmbeddedImages = true;
options.ImageIndexingOptions.EnabledForContainerItemImages = true;
options.OcrIndexingOptions.EnabledForSeparateImages = true;
options.OcrIndexingOptions.EnabledForEmbeddedImages = true;
options.OcrIndexingOptions.EnabledForContainerItemImages = true;

// Extracting data from documents
node.Indexer.Extract(documents, passwords, options);

for (int i = 0; i < streams.Length; i++)
{
    streams[i].Close();
}

// Adding extracted data to the index
node.Indexer.Add(extractedData, options);
