> GermanStemmer.cs has numerous string substring errors

> Key: LUCENENET-102
> URL: https://issues.apache.org/jira/browse/LUCENENET-102
> Project: Lucene.Net
> Issue Type: Bug
> Environment: Lucene.Net 2.0 using the GermanStemmer
> Reporter: Stefan Rusek
> Attachments: GermanStemmer.cs.diff
>
>
> When using the german stemmer that is included in the 2.0 release. The
> stemmer will throw ArgumentOutOfRangeException. We have fixed the issue
> in-house but wanted to get the fix incorporated into the actual Lucene.Net
> release so that future users don't have this problem. Below is an example
> stacktrace, and I will attach a diff as well.
> System.ArgumentOutOfRangeException: Index and length must refer to a location
> within the string.
> Parameter name: length
> at System.String.InternalSubStringWithChecks(Int32 startIndex, Int32
> length, Boolean fAlwaysCopy)
