dtSearch 7 Network with Spider
dtSearch Network allows for instant text and field searches across an enterprise network
The built-in Spider can expand the scope of the searchable database beyond "local" data to remote web-based content
Following are some key features of these products:
Terabyte Indexer. dtSearch Desktop and Network can index over a terabyte of text in a single index, spanning multiple directories, emails and attachments, online data and other databases. The products can create and search any number of indexes. Indexed search time is typically less than a second, even across terabytes of data.
Enterprise Searching. The dtSearch product line offers efficient multihreaded searching, with no limit on the number of concurrent search threads. Even with many simultaneous dtSearch Network searches across a very large indexed database, concurrent search time is typically under a second.
Federated Searching and the dtSearch Spider. dtSearch Desktop and Network products provide federated searching across any number of directories, emails (with nested attachments), and databases. The dtSearch Spider adds local and remote, static and dynamic online content to a search. The Spider can index sites to any level of depth, with support for public and private or secure online content, including log-ins and forms-based authentication. dtSearch products support integrated relevancy ranking with highlighted hits across both online and offline data repositories.

MS Office formats: supports
integrated browser-ready image and text in Word (RTF/DOC/DOCX), PowerPoint (PPT/PPTX),
Excel (XLS/XLSX), Access (MDB/ACCDB) and OneNote (ONE); support includes
documents saved from Office 365.
Other “Office” formats, PDF and
other printer formats, compression formats: supports other “Office”
suite formats; EMF Spool (SPL) files; compression formats like RAR, ZIP,
GZIP and TAR; PDF, PDF Portfolio, and many encrypted PDFs.
Emails and attachments: supports integrated browser-ready images, text and
attachments in Outlook/Exchange (PST/OST/MSG) and Thunderbird (MBOX/EML);
support includes emails saved from Office 365.
Recursively embedded objects:
supports recursively embedded objects and images in supported email types
and MS Office formats. For example, the dtSearch document filters would
support an email attachment consisting of a ZIP container including both a
PDF and an Access database, where the latter also includes an embedded
PowerPoint with embedded images.
Full list of supported document types.
Federated searching and
the dtSearch Spider. dtSearch products provide federated search across
any number of directories, emails (with nested attachments), and databases.
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

Document filter APIs.
All developers APIs (C++, Java and .NET through current versions) make available
to developers dtSearch’s text parsing, extraction, conversion and
An “object extraction” API lets developers
navigate through the structure of each embedded object as a hierarchy, and
optionally extract each object, such as an image in an MS Word file embedded
in an MS Access database, compressed and attached to an email.
General dtSearch Engine licenses include the
document filters along with dtSearch indexing and searching functionality.
The document filters are also available for
separate license for developers requiring text parsing, extraction and
conversion “only,” without search.

Japanese and Korean Text With No Word Breaks
Some Chinese, Japanese, and Korean
text does not include word breaks. Instead, the text appears as
lines of characters with no spaces between the words..
Because there are no spaces
separating the words on each line, dtSearch sees each line of text
as a single long word.
To make this type of text
searchable, enable automatic insertion of word breaks around
Chinese, Japanese, and Korean characters, so each character will be
treated as single word.
In Options > Preferences > Letters and Words, check the box to
“Insert word breaks between Chinese, Japanese, and Korean characters
dtSearch Developer API: set
dtsoTfAutoBreakCJK in Options.TextFlags.
Analyzer API Integration
In addition to the extensive
alphabet customization options available across the dtSearch product
line, the dtSearch Engine also includes a
Language Analyzer API that can be used to integrate
morphological analyzers and custom or dictionary-based word breakers
into the dtSearch Engine indexing process.
The dtSearch Engine also includes an
API for substituting a non-English language thesaurus for the
existing English-language one.
The Rosette Linguistics Platform
helps unlock the meaning of unstructured text by determining the
language, and identifying the basic linguistic features and
structure. Relying on code that is unique to each particular
language, Rosette results in highly accurate Chinese, Japanese,
Korean, and other international language morphological analysis..
The Rosette Linguistics Platform
integrates with dtSearch search functionality through the dtSearch
Engine’s Language Analyzer API. Essentially, the dtSearch Engine
API passes blocks of Unicode text to the Rosette Linguistics
Platform and accepts back words to index.
