We’re happy to announce the GroupDocs.Search for .NET 25.11 release, available as of November 2025. This update brings a small but useful enhancement for plain‑text files and a fix that makes text extraction with backup privileges reliable.

What’s new in this release

  • [Enhancement] Implement default text extractor for plain‑text file types (SEARCHNET‑3524) – the library now includes a built‑in extractor for .log files, so you can index those documents without writing a custom extractor.

Fixes and enhancements

  • [Fix] Error during text extraction with backup privileges resolved (SEARCHNET‑3522) – the Extractor now works correctly when ExtractionOptions.UseBackupPrivilege is set to true.
    Public API change: a new TempFolder property was added to GroupDocs.Search.Common.ExtractorSettings to let you specify a temporary working directory.
using GroupDocs.Search;
using GroupDocs.Search.Common;

// Configure a temporary folder for the extractor (required for the fix)
Extractor extractor = new Extractor();
extractor.Settings.TempFolder = @"C:\Temp\SearchExtractor";

// Enable backup privilege when extracting
ExtractionOptions options = new ExtractionOptions
{
    UseBackupPrivilege = true
};

// Load the protected document
Document document = Document.CreateFromFile(@"C:\Docs\protected.docx");

// Perform extraction
ExtractedData data = extractor.Extract(document, options);
// ...process `data` as needed
