    BETHESDA, Md., May 25 /PRNewswire/ -- dtSearch Corp., a leading supplier
 of enterprise, end-user and developer text retrieval software, announces
 Version 7 of its product line.  The product line can now instantly search
 terabytes of text across a desktop, network, Internet or Intranet.  The
 release covers:  dtSearch Web with Spider, dtSearch Desktop with Spider,
 dtSearch Network with Spider, dtSearch Publish and the dtSearch Text Retrieval
     Previously, the dtSearch index format could hold from 4-8 gigabytes of
 text per index.  The Version 7 index format can index over a terabyte of text
 in a single index.  Search time with over a terabyte of text is typically less
 than a second.  As with previous versions, a single search can span any number
 of indexes.
     Product line overview.  All dtSearch products share the same core search
 and display functionality, including:
      -- over two dozen indexed, unindexed, full-text and fielded data search
      -- display of HTML, XML and PDF files with highlighted hits and with
         embedded images, links and formatting intact
      -- built-in HTML converters for display of word processor, database,
         spreadsheet, email (including attachments), ZIP, Unicode, etc. files,
         with highlighted hits.
     The dtSearch Spider embedded in multiple dtSearch products provides
 integrated searching of remote Web site content, along with locally-available
 data.  In addition to support for the file formats above, the dtSearch Spider
 can also index and search dynamically-generated content, such as ASP/ASP.NET,
 MS CMS, MS Sharepoinet, etc.
     The Spider can follow links vertically within a web site, or horizontally
 across web sites, to any specified level of depth.  The Spider supports public
 sites, secure content HTTPS sites, password-accessible sites and forms-based
 authentication.  After a search, dtSearch provides integrated relevancy-
 ranking and other display of local and Spidered content, including WYSWYG
 display of Web-ready content with highlighted hits.
     dtSearch Web quickly publishes a large volume of instantly searchable data
 to an Internet or Intranet site, with Spider functionality.  The dtSearch
 Engine lets developers add dtSearch's built-in file format support and
 searching to Web-based and other applications.  The dtSearch Engine API
 support includes SQL, Delphi, Java, C++, C++.NET, C#, VB.NET and ASP.NET.
     dtSearch Desktop instantly searches popular file types on a PC, while
 dtSearch Network searches across a network, running in a client/server
 capacity.  dtSearch Publish can quickly publish an instantly searchable
 document collection to CD, DVD or similar media.   The product can also mirror
 an existing Web site on CD/DVD.  The resulting CD/DVD application can run
 without installing anything on the user's hard disk.
     The dtSearch product line offers over two dozen indexed, unindexed,
 fielded and full-text search options.  These include:  fuzziness adjustable
 from 0 to 10 (to sift through typographical and spelling errors),
 synonym/concept/thesaurus, boolean (and/or/not), natural language relevancy
 ranking (by hit term frequency, density and rarity), positional scoring
 ranking, phrase, phonic, wildcard, bilateral proximity, directed proximity,
 stemming, numeric range, user-defined variable term weighting, and
 international language support through Unicode.
     Special forensically-oriented features include:  (i) automatic parsing of
 text segments in large data blocks, such as those recovered through an
 "undelete" process, from unallocated computer space, or from partially
 recovered file fragments; (ii) language recognition algorithms for detecting
 text in a large variety of languages (Western European, other European,
 Middle-Eastern, etc.); (iii) a proprietary filtering algorithm for scanning
 recovered data blocks using multiple text encoding detection methods; and (iv)
 automatic recovery of text from corrupt forensically-retrieved documents.
     Pricing is $199 for dtSearch Desktop with Spider, from $800 for dtSearch
 Network with Spider, from $999 for dtSearch Web with Spider, and from $2,500
