The Smart Choice for Text Retrieval® since 1991

New ASP.NET Core Demo


dtSearch is pleased to announce the release of version 7.91 of the dtSearch product line.  The new release is recommended for all users, particularly users of dtSearch Web/Engine.

This version fixes a denial of service vulnerability affecting searches in dtSearch Web, and potentially other web-facing applications using the dtSearch Engine that accept very long search requests.

For dtSearch Engine users, the new release expands the .NET Standard / ASP.NET Core sample code to cover faceted search and multicolor hit-highlighting. (The previous dtSearch Engine release included a cross-platform dtSearch .NET Standard / .NET Core / Xamarin SDK for Windows, UWP, Linux and macOS, plus iOS and Android in beta. This new SDK comes as an addition to the dtSearch Engine’s existing C++, Java and .NET APIs. All SDKs cover both dtSearch document filters and search functionality.)

A beta demo page demonstrating the new  .NET Standard / ASP.NET Core sample code with faceted search and multicolor hit-highlighting is available here.

Please see the release notes for details and information on other improvements and bug fixes.

Announcing the Release of Cross-Platform dtSearch® .NET Standard/.NET Core/Xamarin SDK for Windows, UWP, Linux and macOS, plus iOS and Android in beta
dtSearch enterprise and developer products instantly search terabytes of online and offline data with over 25 search options

dtSearch Corp. announces the release of Version 7.90 of the dtSearch product line. This version adds a new cross-platform dtSearch Engine .NET Standard SDK with Xamarin and .NET Core APIs and sample code. The release covers Windows, UWP, Linux and macOS. iOS and Android versions of these APIs are in beta testing.

The .NET Standard/.NET Core/Xamarin SDK comes as an addition to the dtSearch Engine’s existing C++, Java and .NET APIs. All APIs cover both dtSearch document filters and search functionality. The document filters are also available for separate licensing.

In addition to the dtSearch Engine for developers, the new release also encompasses dtSearch’s enterprise-ready products: Desktop with Spider, Network with Spider, Web with Spider, and Publish. The new version improves summary reporting of index updates to make it easier for users to monitor the results of multiple automatically-scheduled index updates.

Through the embedded document filters, all dtSearch products work with a broad spectrum of data, including “Office” documents, PDFs, compression formats, emails and multilayer nested attachments, online data and databases. General features include:

  • Terabyte Indexer and Multithreaded Searching. dtSearch products can index over a terabyte of text in a single index. The index can cover multiple data sources, including different directories, email stores with attachments, databases and other online data. dtSearch products can create and search any number of indexes, and can search indexes during updates. The products support efficient multithreaded searching, with no limit on the number of concurrent search threads.
  • Over 25 Search Options; International Language Support. The dtSearch product line has over 25 search types, including special forensics search options like the ability to identify credit card numbers and generate and search for hash values. For international languages, dtSearch products support Unicode, including support for right-to-left languages, and Chinese/Japanese/Korean character handling options.
  • Faceted Search and Other Data Classification Options. The dtSearch Engine SDKs supports categorization based on document full-text contents, internal document metadata, database content, or data attributes associated with documents during document indexing. The dtSearch Engine APIs offer faceted searching and other advanced data classification methods.
  • Document Filters. The product line uses dtSearch’s own document filters to parse, extract, convert, etc. data in supported data types including “Office” files, PDF, compression formats, emails and multilayer nested attachments, online data and databases. After a search, the document filters can display retrieved files and other data with multicolor highlighted hits.
  • Federated Searching and the dtSearch Spider. dtSearch products offer federated searching across any number of databases, directories and email repositories. The dtSearch Spider adds local and remote online content to a search. The Spider can index sites to any level of depth, with support for public and secure online content. Federated searching includes integrated relevancy ranking (including multicolor highlighted hits) across both online and offline data.
