dtSearch Desktop/Network

dtSearch Desktop is a powerful and robust information retrieval tool, it enables you to search through terabytes of text in under a second because it builds an index that stores the location of the words in your files.

dtSearch Desktop can search all Microsoft Office formats and the latest PDF 2.0 format, as well as many legacy file formats, and never alters or moves your original files. See here for the full list Article: DTS0103

You can choose to index drives (including removable media), folders, files, Outlook folders or use the built-in Spider to index Web sites.

Uniquely dtSearch Desktop can perform un-indexed as well as "combination" searches to search files that have not been indexed.

dtSearch Desktop has dozens of advanced indexing options to give you complete control over the content of each index. It will automatically collect Meta data from HTML, Word and PDF documents as well as from media files such as MP3, ASF and WMV to allow field searching. Indexes can be automatically updated by using the Windows Task Scheduler to reflect additions, deletions and modifications to your document collection. Each index holds over 1TB of data, create multiple indexes for focused search results.


dtSearch has over 25 indexed and unindexed text search options. Unlike most other search tools, searching is not 'blind' - the word-wheel shows all the words in your documents, simply double-click on a word to enter it into the search query textbox.
