The Domino (Domain Search) Filesystem indexer [edit] on Windows supports path lengths of max 256 chars (MAX_PATH). While Windows OS does somewhat provide support for longer paths, applications also need to support this as well. The Domain Indexer Filesystem should support long file-paths using the \\?\UNC\server\share, or \\?\X:\ notation.
This would require the "longPathAware" element in the applications manifest, and larger filename buffers.
Currently the FileSystem indexer fails on long path-names with (debug enabled):
OUT FTGIndex rc = 3840 (Unknown full text indexing error) - for [X:\10--Projects Acme\...
Error full text indexing document NT00000000 in file system X:\10--Projects Acme\...2021v01.pdf in domain index D:\Domino\Data\ftdomain.di\FS\IDX0: Unknown full text indexing error
Domain Indexer finished indexing File System 'X:\10--Projects Acme\...Unknown full text indexing error
[edit] The Windows operating system is somewhat inconsistent/ convoluted in its support for long path names. The OS itself supports them, but not all standard applications such as File Explorerand CMD do. Linux natively supports 4K path names and is therefore a better choice for indexing file systems from Domino.
