Full-Text Index of all files

[markfeit]

Develop a system for indexing snapshot contents using a full-text indexer such as Xapian. Examples:

Find a specific file within a date range:

% bin/find-file local/home/bob/.bashrc date:2017..2018
Snapshot 2106  2018-05-12 02:23  local/home/bob/.bashrc
Snapshot 1255  2017-01-27 01:19  local/home/bob/.bashrc

Find files by text occurring in the name:

% bin/find-file .bashrc
Snapshot 2106  2018-05-12 02:23  local/home/bob/.bashrc
Snapshot 1957  2017-12-25 01:54  local/home/steve/.bashrc
Snapshot 1255  2017-01-27 01:19  local/home/bob/.bashrc

There will need to be three operations on the index:

• Initial build from all snapshot data
• Add data from new snapshot(s)
• Remove data for snapshots that no longer exist
