dtSearch Corp., a leading supplier of enterprise and developer text retrieval along with document filters, announces beta testing of Version 7.70 of the dtSearch product line. The new version adds multiple improvements to the document filters spanning the dtSearch product line. For customers in need of data parsing, conversion and extraction only, the dtSearch Engine APIs (native 64-bit/32-bit, Win/Linux C++, Java and .NET through 4.x) also make the document filters available for separate OEM licensing.
Document Filters. dtSearch’s proprietary document filters support a broad range of data types (many of which already include combined image and text support):
• “Office” documents: MS Office, OpenOffice, RTF, PDF, etc.; the beta also adds support for Japanese Ichitaro documents
• Emails: MS Exchange, Outlook, Thunderbird, etc., all with nested attachments
• Compression formats: ZIP, RAR, GZIP/TAR, etc.
• Web-ready data: HTML, XML/XSL and PDF—all already with full image (in addition to text) support
• Dynamic data: PHP, ASP.NET, SharePoint, etc.— all already with full image (in addition to text) support
• Databases: SQL including BLOB data (through the dtSearch Engine APIs), MS Access, XBASE, XML, CSV, etc.
The document filters support parsing of all of the above data types as well as text extraction and/or conversion to HTML as required for browser display with highlighted hits.
Embedded Image Enhancements. The new beta extends the document filters to add image support to Word (.doc/.docx), PowerPoint (.ppt/.pptx), Excel, (.xls/.xlsx), Access (.mdb/accdb), RTF, and email files including Thunderbird (mbox/.eml), and Outlook (.pst/.msg) files. The beta displays these formats showing highlighted hits in context with both text and now images.
Multi-Level Nested File Enhancements. The dtSearch document filters also support documents and images in multi-level nested configurations. For example, the beta would support not only viewing images in an email file, but also images in a PowerPoint embedded in a Word document attached as a zipped file to an email message. A new “object extraction” API lets developers navigate through the structure of each embedded object as a hierarchy, and optionally extract each object.
Spider. The Spider works with local and remote, static and dynamic web content. Hit-highlighted searching can span any level of site depth, across any number of public and private or secure sites, including support for log-ins and forms-based authentication. The Spider is built into the dtSearch product line, and accessible through a .NET API for programmers.
Terabyte Indexer. dtSearch enterprise and developer products can index over a terabyte of text in a single index, spanning directories, databases, online data, and emails. The products can create an unlimited number of indexes, and simultaneously search them. Indexed search time is typically less than a second, even across terabytes of data. Online indexed searching operates in a “stateless” environment, supporting unlimited concurrent search threads.
Search Options. The dtSearch product line includes 25+ full-text and fielded data search types, including special forensics search options. dtSearch products offer federated or distributed searching with integrated relevancy ranking across any number of different data repositories. The dtSearch Engine APIs also support faceted searching and other advanced data classification objects.
International Language Support. dtSearch products support all Unicode languages, including both right-to-left languages, and special Chinese/Japanese/Korean character options.
The dtSearch Engine. The dtSearch Engine for Win & .NET and the dtSearch Engine for Linux make available dtSearch document filters and instant searching for a wide range of Internet, Intranet and other commercial applications. The SDKs include native 64-bit and 32-bit C++, Java and .NET (through 4.x) APIs. For over a hundred developer case studies, please see www.dtsearch.com/casestudies.html. In addition to standard OEM licenses, the SDK also makes available the document filters for separate OEM licensing.
Other dtSearch Products. The new release also covers dtSearch Web with Spider for quickly publishing instantly searchable data to an Internet or Intranet site, dtSearch Network with Spider for instantly searching across a network, dtSearch Publish for publishing searchable data to portable media, and dtSearch Desktop with Spider for desktop search.
