Reduce repo indexer disk usage #3452

ethantkoenig commented Feb 3, 2018

Reduces disk usage of the repo (i.e. code) indexer:

  • Disables bleve's _all field (which meant that we were previously storing everything twice)
  • Use the bleve unique token filter (blevesearch/bleve#739), since we only display the first occurrence of the search term.

I saw as roughly 3x (1.5GB -> 500MB) reduction in disk usage as a result of these changes (of course, mileage will vary depending on what type of text/code you are indexing).

Also introduces a migration-like versions to the issue and repo indexers to facilitate changes (which will typically require rebuilding the index).

Yes, this PR shamelessly pulls in as a dependency to facilitate tracking indexer versions and migrations; I am aware of no other alternatives.

Should this use numericFieldMapping?
