Hi

I'm trying to make an autocompletion, who gives higher score for typed word positions. Sorted by score and then name.

**My goal:**

typing "pet"

result:

```
peter christensen
peter christian grau
peter christian reumert krogsgaard
peter bruun christensen
anders petersen

```

typing "peter chr"

result:

```
peter christensen
peter christian grau
peter christian reumert krogsgaard
peter bruun christensen

```

Above succeed and I was happy, but then something strange happening, when there are duplicates "peter christensen". Now the result looks like this:

```
peter christian grau
peter christian reumert krogsgaard
peter christensen
peter christensen
peter bruun christensen

```

And I want this:

```
peter christensen
peter christensen
peter christian grau
peter christian reumert krogsgaard
peter bruun christensen

```

Please help?
