Products：Desktop/Network/Publish/Web/Engine

The dtSearch product line generally shares the same core feature set:
Terabyte Indexer. dtSearch products can 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.
File Formats and Databases. dtSearch products include integrated file parsers and converters for a wide range of popular file types. dtSearch products display existing web-ready content (HTML, PDF, XSL/XML, etc.) with highlighted hits, and with all images, links and formatting intact. For other file types (MS Office, OpenOffice, ZIP, etc.), built-in proprietary converters render these document types as HTML, with highlighted hits, for display in a web browser. The dtSearch Engine includes a data source API for indexing SQL-type databases and other non-file data (including BLOB data).
Spider. The dtSearch Spider adds local or remote website content to a searchable data collection. The Spider supports public sites, intranets, HTTPS, password-accessible sites, and forms-based authentication sites. The Spider supports both static and dynamic (ASP.NET, PHP, MS CMS, SharePoint, etc.) web-based content, indexing to any level of vertical or horizontal depth. dtSearch products support integrated searches of local and remote content, including WYSIWYG hit highlighted display of web-ready data.
Search Features. Full-text and fielded data search options include: distributed or federated search options with integrated hit-highlighted display, fuzziness adjustable from 0 to 10 (to sift through typographical and spelling errors), synonym/concept/thesaurus (through a built-in thesaurus and/or user-defined synonym rings), boolean (and/or/not), phrase, phonic, wildcard, bilateral proximity, directed proximity, stemming, natural language/vector-space relevancy ranking, variable term weighting, positional scoring, field-based relevancy ranking, data classification and filtering objects, numeric range searching, advanced date recognition, unindexed search (in addition to indexed search), and special forensics search options (text filtering of forensically-recovered data, credit card search, email search, etc.).
International Language Support. Built-in Unicode support covers hundreds of international languages (including right-to-left languages and Chinese/Japanese/Korean character processing options).

The following dtSearch products are all included in the new Version 2023.02 release:
dtSearch Desktop with Spider instantly searches files on a PC. dtSearch Network with Spider searches across a network. Both instantly search and display, with highlighted hits, a wide variety of file types, including email messages along with the full text of email attachments. Through the Spider, both applications can also add web content to a local or network search.
dtSearch Web with Spider quickly publishes a large volume of instantly searchable data to an IIS Internet or Intranet site. dtSearch Web works as a "point and click" solution, with no programming required. The Spider provides integrated support for local and remote web site data.
dtSearch Publish enables users to easily publish instantly searchable document collections or web site content to portable media (CDs, DVDs, external hard drives, etc.).
The dtSearch Engine lets developers add dtSearch functionality to 32-bit and 64-bit applications. The dtSearch Engine for Win & .NET supports C++, Java and .NET, including a .NET Spider API. The new release provides expanded sample code for use with Microsoft's most recent Visual Studio version The dtSearch Engine for Linux supports C++ and Java.
