FileSeek vs Open Semantic Desktop Search

FileSeek is a Windows file-search app that can look through local paths, network shares, and synced cloud folders such as Dropbox and OneDrive. Queries can be simple, use regular expressions, or use advanced text syntax. It uses multithreading and does not depend on background indexing. Advanced IFilters allow searches to process non-text files such as Excel and PDF. Pro adds saved search profiles that can sync between computers, multiple search tabs, and CSV or HTML result exports. The free plan is limited to personal use and lacks those Pro features. Pro Standard costs $19, paid once for a lifetime license for one computer; other lifetime licenses cover personal computers, a site, or company-owned sites. The current release supports Windows 10 version 1607 or higher, Windows 11, and Windows Server 2016, 2019, and 2022. Downloads include an installer, ZIP build, and MSI installer, and FileSeek can also be installed using WinGet. SHA1 hashes are published to help check downloads. Support is included with free and Pro licenses.

Open Semantic Desktop Search is free, open-source software for full-text and semantic search, text analytics and mining across large document sets. Its desktop edition comes as a virtual machine appliance for import into VirtualBox; configured shared folders point to documents, and indexing starts when the machine launches. Search supports wildcards, Boolean AND/OR/NOT and fuzzy matching. Multilingual semantic search uses a thesaurus to find synonyms, narrower terms and aliases, while stemming helps find other word forms. Interactive facets group metadata such as authors, organizations, people, dates, tags and document types. Previews can display PDFs, extracted text, table rows and images. Analysis tools include date charts, word clouds, word lists, network graphs and interactive maps. OCR can recognize text in images and scanned PDFs. Connectors include files, feeds, websites, SQL databases, MediaWiki and IMAP email. The desktop appliance is for a single user; a separate server installation is aimed at organizations and research teams. The multilingual virtual machine image is a 4 GB download, and the German desktop image is listed as coming soon.
