Maximum Programmer Flexibility

Includes advanced multithreaded operation for use with Active Server Pages (ASP) and .NET.

Has extensive sample source code:

•through a COM interface for Visual Basic, ASP and Delphi.

•through a function-call interface for C++ and Visual C++.

•through JNI for Java.

•for an ADO database application.

Includes sample source code for dtSearch Web in both ASP and ISAPI versions.

Has sample C++ code for dtSearch Publish.

Has sample code to implement FindPlus® distributed searching using an XML-based protocol for exchanging and aggregating search information.

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, 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).

•(For more information, see Search Features – Full-Text, Fields.)

Uses proprietary indexing and searching algorithms engineered for scaleability.

•Indexed search time is generally instantaneous.

•Indexing is optimized to maintain consistent speed over even the largest document collections.

•(For more information, see Capacity & Speed.)

Includes unindexed search options for filtering purposes.

Instant Support for Multiple File Types

Automatically supports PDF, HTML, XML, word processor, database, spreadsheet, email, ZIP, and more.

Has built-in Unicode support (Unicode file support works on Win 95/98/NT/ME/2000/XP).

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.

•(For more information, see Compatability, Display, OCR.)

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.

Supports complete hierarchical field structures in XML for searching limited to specific combinations of fields and sub-fields (as well as full-text).

A sample ADO database indexing application provides indexing and searching of SQL and other COM data sources.

Supports hit highlighting, as well as multiple hit and file navigation options, in all of the above. (See also Fields and Compatability, Display, OCR.)

Other Data Input/Output Support

Allows search results serialization as an XML or URL-encoded stream.

Has a data source API for supplying plain text or binary documents directly to the indexing engine using C++ or COM.

Has a file format API for the addition of custom file formats.
