| - What is search? scan text, use BM/BMG/KMP or regex or recursive-descent.. or suffix tries.. or you can search through the zip-format (BWT) | |
| - Inverted index: words to documents, instead of crawling documents for words. | |
| - SET per word with items for each docid, using redis' intersection for AND, union for OR | |
| - "Simplest example that will be useful..[but it wont be that useful... buy the book!]" | |
| - Demo of his editor.. its on sourceforge. | |
| - Tokenization, stop words in some python code.. "with this stuff, we're going to implement search" already has failing tests written.. live coding, so not many notes... buy his book. | |

I've been playing around with trying to make it as simple as possible to start logging a few metrics with as little effort in setup as possible.
As I was working on Papertrail I came up with a couple interesting ideas, some of which were inspired by OpenTSDB.
In this example we are pretending we're processing emails as background jobs and would like to track how many we've sent over time.
