The latest release of the dtSearch product line of text retrieval and file conversion software includes a native 64-bit .NET 4 SDK for the dtSearch Engine.

The .NET 4 SDK covers the Spider API for indexing local and remote, static and dynamic web-based content, including both public and secure Intranet data.  The .NET 4 release also has a sample application for the Azure cloud platform. In addition the new SDK offers performance enhancements for faceted searching involving millions of document metadata tags or database records.

The new release encompasses the rest of the dtSearch product line:

• dtSearch Web with Spider for publishing searchable data to an Internet or Intranet site
• dtSearch Network with Spider for  searching across a network
• dtSearch Publish for publishing searchable data to portable media
• dtSearch Desktop with Spider for desktop search.

The dtSearch Spider adds local or remote website content to a searchable data collection. The Spider provides integrated hit-highlighted searching of dynamic content like SharePoint, CMS, PHP and ASP.NET, as well as static content like HTML, PDF, XSL/XML. Searches can span any level of depth, across any number of sites, including public sites, intranets, and secure and password-accessible sites. A .NET Spider API (including the new .NET 4 version) makes the Spider functionality accessible to programmers.

All dtSearch products feature a Terabyte Indexer enabling them to index over a terabyte of text in a single index. They can also create and simultaneously search an unlimited number of indexes. Indexed search time is typically less than a second, even across terabytes of data. The new release also offers performance enhancements to a forensic indexing version of the terabyte indexer.

By embedding the dtSearch file parsers and converters the products display existing web-ready content like HTML, PDF and XML/XSL with highlighted hits, and with images, links and formatting intact. Other file types are converted to XML or HTML for browser-based display with highlighted hits. The current version supports MS Office through MS Office 2010,  OpenOffice, CSV, ZIP, etc.They can also index and search email messages from Exchange, Outlook and Thunderbird, as well as attachments, nested attachments, and zipped attachments.

dtSearch offers over 25 full-text and fielded data search options, including advanced federated search options and special forensics features. Unicode support covers all Unicode languages, including support for right-to-left languages and Chinese/Japanese/Korean character processing options. It offers a wide range of API filters and objects to support categorization via document full-text contents, document fields, database contents, or data attributes attached during indexing. The new SDK enhances hierarchical sorting or "faceted search" performance across data sets with millions of metadata tags.
