We all know how things start off fine, users can quickly create OneNote Notebook sections and pages and can often remember where they squirrelled away important information when they have a small number of pages. Over time the volume of informations grows, informations gets duplicated, information becomes out of date, people leave or move to new posts...

Trying to find information, weed out duplicate or obsolete data, or ensure compliance gets harder over time as the amount of information grows, that's when you need a heavy duty search tool like dtSearch Desktop.

Dynamic content such as SharePoint can be indexed using the Spider built into dtSearch Desktop/Network. However, the log-in mechanism can only handle single-page log-in forms and is not suitable for SharePoint Online. 365 Indexer solves this problem by connecting directly to multiple Microsoft 365 accounts via the Microsoft Graph API to enable dtSearch Desktop to search SharePoint Online and OneNote for Windows 10 data.*

*PDF attachments are stored compressed in the index, this requires dtSearch Desktop/Network 7.96 or later with the 'Standard' viewing option for PDF files. Not supported in dtSearch Web.

Edit an external file to translate all the visible text into any language supported by Unicode.

* NOTE: Microsoft E5 licenses (or Office 365 E3 with the Advanced Compliance add-on) include the Advanced eDiscovery feature that uses dtSearch to extract text of non-Microsoft file formats.

You do not need an E3 or E5 license, 365 Indexer uses the dtSearch Engine to index ALL file formats, enabling search results with hit-highlighting for Microsoft and non-Microsoft file formats and all of the advanced search and reporting options built into dtSearch Desktop/Network.
