What is Qsirch?

Qsirch is a fast, full-text search engine that enables you to find files based on filename, content, and metadata. You can choose from a variety of search options to quickly find documents, images, videos, emails, and other NAS-based files. Qsirch’s search functions are also available using a companion mobile app, browser extension, and Mac® Finder. Qsirch is useful for both homes and businesses, allowing home users to quickly find movies, songs or photos and helping business users increase their productivity by cutting down the time spent hunting for files.

How Qsirch works?

Qsirch automatically indexes all NAS-based files, allowing users to quickly find the files they need. Qsirch and QTS share the same privilege settings, so users can only find the files which they are authorized to. Administrators can remove shared folders from being indexed to protect sensitive data, and can also exclude backup folders from being indexed to avoid unnecessary system resource usage.

Note:Qsirch uses NAS CPU/ RAM resources when indexing files. Upon finishing, Qsirch will release the system resources. The indexing process will take longer when enabling Qsirch for the first time or when a lot of NAS files are added/removed.
