Solr uses "stemming" for indexing/searching words. After that it
searches those stemmed words, it doesn't do prefix searching by default.
So:

1) You don't have any mails with a word "testin" in it.

2) "testing" probably gets stemmed to "test", and you get a combined
result of "test", "testing", "tests" and maybe some other words.
