Having indexed the Enron email dataset, with a two-field text index with default weightings, I'm seeing unexpected behaviour when searching for phrases. It appears terms are being stemmed and stop words removed within a phrase:

> db.getCollection("emails").runCommand("text",

{ "search" : "\"the scrimmage\"",limit:1 }

);

"queryDebugString" : "scrimmag||||the scrimmage||"

> db.getCollection("emails").runCommand("text",

{ "search" : '"the scrimmage"', limit:1 }

);

"queryDebugString" : "scrimmag||||the scrimmage||"

This behaviour was first spotted by a MongoDB user at the FTS Hackathon in London.
