New dtSearch Document Filter Products

Enterprise and developer text retrieval software company dtSearch has announced Version 7.70 of the dtSearch product line. The release sees improved document filters embedded across the entire dtSearch product line.

The new version 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 release displays these formats showing highlighted hits in context with both text and images. The release also adds support for Japanese Ichitaro documents.

dtSearch's proprietary document filters support a broad range of data types from "Office" documents: MS Office, OpenOffice, RTF, PDF to emails and also MS Exchange, Outlook, Thunderbird — all with nested attachments.

Compression formats are also supported: ZIP, RAR, GZIP/TAR, etc. as are web-ready data (including image and text support): HTML, XML/XSL, and PDF, plus dynamic data (including image and text support): PHP, ASP.NET, and SharePoint. Database is also included: SQL including BLOB data (through the dtSearch Engine APIs), MS Access, XBASE, XML, and CSV.

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.

The release also increases support for documents and images in multi-level nested configurations. For example, the new version supports 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.

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.

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.

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.
