Incorrect use of StreamReader in MoreLikeThis
---------------------------------------------
Key: LUCENENET-450
URL: https://issues.apache.org/jira/browse/LUCENENET-450
Project: Lucene.Net
Issue Type: Bug
Components: Lucene.Net Contrib
Affects Versions: Lucene.Net 2.9.2, Lucene.Net 2.9.4, Lucene.Net 3.x,
Lucene.Net 2.9.4g
Reporter: Itamar Syn-Hershko
In the MoreLike this implementation (looking at the trunk), line 772
incorrectly creates a new StreamReader instead of using StringReader. This
causes the following exception to be thrown, since the ctor expects a file path
and not an input string:
System.ArgumentException: Illegal characters in path.

Simply replacing StreamReader with StringReader will do the job
