language support

BETHESDA, MD (November 27th, 2007) dtSearch Corp., a leading supplier
of enterprise and developer text retrieval software, announces Version
7.5 of the dtSearch product line. dtSearch products instantly search
terabytes of data, in a wide variety of formats, across a desktop,
network, Internet or Intranet.

New 64-bit version. The new release includes a native 64-bit version
of the dtSearch Engine for Win & .NET (for .NET 2.0/3.0) for
developers to integrate into web-based and other applications. The 64-
bit version provides full API access to dtSearch's terabyte indexer
and search functionality, file format and database support (including
SQL BLOB data).

International language enhancements. dtSearch products include
international language support through Unicode, covering hundreds of
international languages. The new version adds improved searching of
Chinese, Japanese and Korean text presented without spaces between
words. The new version also offers improved developer API integration
with third-party international language morphological analyzers like
those from Basis Technology (www.basistech.com).

Product line overview. Terabyte indexer; file parser/converters. All
dtSearch products can index over a terabyte of text in a single index,
as well as create and simultaneously search an unlimited number of
indexes. Indexed search time is typically less than a second, even
across terabytes of data.

Along with the terabyte indexer, all dtSearch products generally share
the same feature set:
* over two dozen indexed, unindexed, full-text and fielded data search
options
* display of web-ready content (HTML, PDF, XSL/XML, etc.) with
highlighted hits and with all images, links and formatting intact
* built-in HTML converters for hit-highlighted display of other
popular file types (MS Office, OpenOffice, Vista XML Paper
Specification (.xps), ZIP, etc.)
* distributed or federated search options, with integrated display of
local and remote content

Spider. The product line also embeds the dtSearch Spider, providing
support for:
* public sites, secure content HTTPS, password-accessible sites, and
forms-based authentication
* searching of web-based content to any specified level of horizontal
or vertical depth
* searching of static content (HTML, PDF, XSL/XML, etc.) and dynamic
content (ASP.NET, MS CMS, SharePoint, etc.) with highlighted hits and
with all images, links and formatting intact
* integrated relevancy-ranking of Spidered and non-Spidered content
(all with highlighted hits)

Search options. Indexed, unindexed, fielded and full-text data search
options include: fuzziness adjustable from 0 to 10 (to sift through
typographical and spelling errors), synonym/concept/thesaurus (through
a built-in thesaurus and/or through user-defined synonym rings),
boolean (and/or/not), phrase, phonic, wildcard, bilateral proximity,
directed proximity, stemming, numeric range, natural language/vector-
space relevancy ranking, variable term weighting, positional scoring,
field-based relevancy ranking, data classification and filtering
objects, special forensics search options, and Unicode support for
hundreds of international languages (including the new Asian language
enhancements).

dtSearch Engine. The dtSearch Engine for Win & .NET, now in native 64-
bit and 32-bit versions, lets C++, Java, COM and .NET developers add
dtSearch terabyte indexer and file format support to web-based and
other applications. For example, the dtSearch Engine includes a
choice of an ADO.NET API (including a native 64-bit .NET 2.0/3.0
version), a Java API, a C++ API and a COM API for indexing and
searching SQL-type databases, along with associated BLOB data. The
dtSearch Engine also provides a .NET API (including a .NET 2.0/3.0
version) for the dtSearch Spider. The dtSearch Engine comes in a
Linux version for C++ and Java developers.

Other dtSearch products. 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-residing content to a local or network search.

dtSearch Web with Spider quickly publishes a large volume of instantly
searchable data to an Internet or Intranet site. The Spider expands
the scope of the searchable database to static and dynamic content on
other sites.

dtSearch Publish offers easy publishing of an instantly searchable
document collection to CD, DVD, portable harddrive, and the like. The
product can also mirror an existing web site on CD/DVD.
