dtSearch Engine for Win & .NET
dtSearch Engine for LINUX

Incorporate industrial-strength text retrieval technology into your own
applications. Royalty-free and royalty based licensing to suit applications
from a single-server to high volume distribution in your own products.

Proven Technology

	dtSearch Corp has been producing text search and retrieval software since 1991.
	Hundreds of commercial applications incorporate the dtSearch Text Retrieval Engine. (See Case Studies)
	dtSearch Desktop, dtSearch Network, dtSearch Publish, and dtSearch Web all use the same dtSearch Text Retrieval Engine technology that is licensed to developers.

Maximum Programmer Flexibility
(Note: Linux version has only Java and C++ API)

	Advanced multi-threaded operation (See Intel Partner Success Story)
	Extensive sample source code:
	NET, ASP.NET 1.1 - 4.0 through a function-call interface for C++ and Visual C++. through JNI for Java. through ADO.NET for database applications. through a COM interface for Visual Basic, ASP and Delphi.
	Sample code in all supported languages, including sample MSFT Azure (cloud) application.

Unparalleled Intelligent Searching

	Provides API access to over two dozen precision search options:
	Search features include synonym/concept/thesaurus, fuzziness adjustable from 0 to 10, boolean, phrase, wildcard, proximity, stemming, numeric range, regular expressions, natural language relevancy-ranked by hit density and rarity, and variable term weighting. Search features can be used alone or in almost any combination (regardless of complexity).
	Uses proprietary indexing and searching algorithms engineered for scalability.
	Indexed search time is generally less than a second. Indexing is optimised to maintain consistent speed over even the largest document collections.
	Includes unindexed search options for filtering purposes.

Instant Support for Multiple File Types

	Automatically supports PDF, HTML, XML, word processor, database, spreadsheet, e-mail, ZIP, and more.
	Built-in Unicode support
	Highlights hits and provides multiple hit and document navigation options in all supported file types.
	For HTML and PDF files, hits are highlighted on the original document, so all embedded links, images, and formatting appear exactly as in the original document. For other file types, built-in HTML converters generate HTML for hit highlighted display in a Web browser.

Extensive Field and Database Support

	Automatically supports fields, document properties, and summary information (along with full-text searching) in HTML, PDF, MS Word, Access, Excel, PowerPoint, etc.
	Complete hierarchical field structures in XML for searching limited to specific combinations of fields and sub-fields (as well as full-text).
	Sample ADO database indexing application provides indexing and searching of SQL and other data sources.
	Hit highlighting, as well as multiple hit and file navigation options, in all of the above.

Other Data Input/Output Support

	Search results serialisation as an XML or URL-encoded stream.
	Data source API for supplying plain text or binary documents directly to the indexing engine.
	External File Parser API for the addition of custom file formats via an external DLL.

Updates & Support

	Product updates and technical support are free for one year with all developer products.
	Technical support is to a single point of contact for developer and multi-user licenses.

dtSearch Web

dtSearch File Converters & Parsers can also be licensed separately for use with other search engines or for non-search products.
