dtSearch Corp., a supplier of enterprise, end-user, and developer text retrieval software, has announced Version 6.4 of its dtSearch product line. dtSearch products are designed to instantly search text across a desktop, network, Internet, or Intranet. dtSearch products also serve as tools to aid in publishing large document collections to Web sites or to CD/DVD, with instant text searching. Products include: dtSearch Desktop with Spider, for searching file types on a PC; dtSearch Network with Spider, for searching across a network; dtSearch Web with Spider, for publishing a large volume of searchable content to a Web site; dtSearch Publish, for publishing a searchable document collection to CD or DVD, or mirroring an existing Web site on CD or DVD; and dtSearch Text Retrieval Engine, for Win & .NET and for Linux, for developers to add dtSearch's built-in file format support and searching to Web-based and other applications.

In addition to "vertical" searching of pages linked from a URL, the Spider can now "horizontally" crawl sites linked to a URL. (In keeping with the broader reach of the dtSearch Spider, the new version also adds options to limit indexed data by file size, file number, time on a Web site, etc.) The Spider also now supports forms-based authentication. Along with the Spider enhancements, dtSearch Web adds new options to the set-up wizard's search form generation, such as date range control, automatic generation of field searching controls, and stylesheet-based search form and search results formatting. dtSearch Publish uses a version of dtSearch Web on its CD/DVDs, along with a mini HTTP server. The dtSearch Text Retrieval Engine, available in both Win & .NET and Linux versions, currently supports SQL, Delphi, Java, C++, C++.NET, C#, VB.NET, and ASP.NET. The new version adds a new native .NET sample application for indexing and searching any database accessible via ADO.NET. The new version also includes Java API enhancements.
