Proven Technology

  • dtSearch Corp has been producing search and retrieval software since 1991.
  • Hundreds of commercial applications incorporate the dtSearch Engine. (See Case Studies page)
  • dtSearch Desktop, dtSearch Network, dtSearch Publish, and dtSearch Web all use the same dtSearch Engine technology that is licensed to developers.
  • Joining the existing Windows and Linux SDKs, this new Android Engine supports Intel and ARM processors and requires Android 9 (Gingerbread) or later. Featuress Java and C++ APIs.

    The Java API is identical to the Windows and Linux versions.

    The C++ API is also identical to the Windows and Linux versions, with some feature differences from the Windows version:

    • The Language Analyzer API and External File Parser API are not supported
    • Regular Expression support is included, using the POSIX Extended syntax. (Windows and Linux both use TR1 regular expressions.)
    • RAR support is not included


Unparalleled Intelligent Searching

Provides API access to over twenty five precision search options:

  • Search options 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 options 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. Over 1Tbyte of data per index.
  • Includes unindexed search options for filtering purposes.

  • For HTML and PDF files, hits are highlighted on the original document, 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)
