only one match

[This script](https://gist.github.com/juliangruber/7180723) searches for `ma` in a database full of all possible 3 character names, and it should find everything from `maa` to `maz`, but only finds `mas`.

Here is the test output:

``` bash
$ node index.js
inserted 17576 values (took 1976ms)
querying for ma
{ name: 'mas' }
{ indexHits: 1, dataHits: 1, matchHits: 1 }
1 out of 17576 names match (took 274ms)
```
