Operating systems supported

Supported: Windows versions 7 through 11 and Windows Server versions 2008 through 2022.

Windows RT is not supported.

Both 32-bit x86 and 64-bit versions of Windows are supported.  (Under 64-bit versions of Windows, the 64-bit executables are installed in the dtSearch bin64 folder.)

Web Browser

dtSearch Desktop also requires that Internet Explorer is installed. Internet Explorer does not have to be your default browser (you can still use Netscape, Opera, or any other browser). dtSearch just needs certain components that are only available if Internet Explorer is installed on the computer.

Hardware Requirements

dtSearch Desktop is designed for systems with a screen resolution of 1024x768 or higher.

Installation takes about 130 megabytes of hard disk space, depending on the options selected.

Additionally, you should have enough free space on the hard disk to build indexes of your documents. A dtSearch index takes about 1/3 the size of the original documents. Please see the article on Index Size for more information.

Recommended memory size is 8 Gb or more.  dtSearch itself requires about 10-20 Mb of memory to search.  Indexing can be done with as little as 30 Mb but more memory will result in faster performance.  

Performance Recommendations

1. Do not put dtSearch indexes on a compressed drive or folder. For example, do not use NTFS compression or encryption on dtSearch indexes. dtSearch indexes are internally compressed, so you will not reduce their size much, and operating system file compression can slow index access considerably. (dtSearch performance is not affected much if the documents are stored in a compressed drive or folder. It is only the indexes that should not be compressed.)

2. For best performance, use a defragmentation utility to keep your hard disk defragmented, and keep the hard disk at least 25% empty so the defragmentation utility can run efficiently.

3.  Index updates will be faster and more reliable if dtSearch Desktop runs on the machine where the index is stored.   It matters much less where the documents are located, because dtSearch just needs to read each document once to index it.   

Network with Spider
dtSearch Network allows for instant text and field searches across an enterprise network

• Proprietary algorithms provide very fast performance on even the largest networks.
• Search time, even with many simultaneous searches of a large indexed database, is typically under a second.
• Includes all of the convenient features of dtSearch Desktop with the dtSearch Spider.
• For enterprise-wide use, has features like support for multiple languages and sharing of indexes and settings among network users.

Publish (portable media)
dtSearch Publish lets you quickly publish an instantly searchable document collection to CD, DVD or other portable media, or mirror an existing Web site to CD, DVD or other portable media.

• dtSearch Publish uses a simple wizard-based setup to create the instantly searchable media.
• For end-users, the media can run with zero footprint, requiring NO INSTALLATION on the end-user’s hard drive.
• Because the dtSearch Publish setup actually runs dtSearch Web on the media, all dtSearch Web features (other than the Spider) are applicable to dtSearch Publish.
• While highly customizable, dtSearch Publish also includes access to the dtSearch Text Retrieval Engine programming API, as an alternative to the dtSearch Publish wizard.

Web with Spider
dtSearch Web is an out-of-the-box solution for publishing instantly searchable documents in both Web-ready and other formats.

• After a simple wizard-based setup, visitors can instantly search the site’s contents with:
  hit-highlighted display of Web-ready file types such as HTML, PDF and XML, including display of images, formatting and links.
  conversion of other file types ("Office," Unicode, ZIP, etc.) to HTML for browser display with highlighted hits.
• Operating through dtSearch Web, the Spider can expand the scope of the searchable database beyond a site's own data to content on a third-party Web sites (both publicly available and secure), including support for a wide variety of content (HTML, XML, ASP.NET, MS CMS, SharePoint, etc.) and WYSWYG hit highlighted displays.
• The product includes numerous customization options, so all aspects of the dtSearch Web display can match the style of the rest of the site.
