The original
DocFetcher
Desktop search that indexes the text inside documents, not just file names.
Replacements
Listings that take over the same core job as DocFetcher.
Recoll
Full-text desktop search across documents and mail, built on Xapian.
Recoll replaces the Java app with Xapian-based indexing and a powerful query language, also covering mail folders, but some formats need external helper programs installed.
AnyTXT Searcher
Local full-text search across documents, PDFs, code and ebooks on Windows.
AnyTXT Searcher offers local full-text search with instant previews, but it is Windows only and closed source, so the indexer cannot be audited.
dnGrep
Search file contents, documents and archives on Windows.
dnGrep searches file contents, documents and archives directly without building an index, is open source under GPL-3.0, and runs on Windows only.
Agent Ransack
Searches file contents on Windows with regular expressions and boolean queries.
Agent Ransack searches file contents on Windows with regular expressions and no index, so it starts instantly but is slow across very large volumes and is closed source.
FileLocator Pro
Indexed content search for Windows with scripting and Office format support.
FileLocator Pro gives indexed content search with Office format support and scripting, but it is Windows only, closed source and paid per user.
Also worth comparing
These listings name DocFetcher as their own alternative, so the relationship runs both ways.
FSearch
Find Linux files quickly through an indexed desktop search.
DocFetcher indexes the text inside documents and archives across Windows, macOS and Linux, but indexing is slow and the Java interface is dated.
