DocFetcher vs SwiftSearch

DocFetcher is a free, open-source desktop application for searching the contents of files stored on a computer. It presents selected results with a text preview and highlighted matches, and search results can be narrowed by file size, type and location. Its query syntax supports AND, OR and NOT, wildcards, phrase and fuzzy searches, proximity search and boosting. Supported content includes Microsoft Office files, Outlook PST, OpenOffice, PDF, EPUB, HTML, plain text, RTF, media metadata, Visio and SVG. It can search ZIP, 7z, RAR and tar archives, including archives nested inside other archives. Users create indexes for folders; the application detects changes while running, and a background daemon records changes while it is closed for processing at the next launch. Portable editions keep indexes and settings in the application folder and can be moved between computers. The maker says the application collects no private data and indexes nothing by default. It runs on Windows, macOS and Linux. The project is legacy software: no new features are planned, though bug fixes and support continue.
