#27 Single ampersand (&) ignored in query

[milnor11]

I cannot find any documentation regarding the following issue, so I am led to believe it is a bug:

If I send the query "Learning & Experience", the queryparser ignores the ampersand and everything that follows it, essentially making the query "Learning".

I know that the indexed document set which I am search contains a document that has the exact string "Learning & Experience" (and it is a .doc file, so the ampersand is not secaped in the file). And I cannot find any documentation stating that a single ampersand (&) needs to be escaped.

If there is a fix to this, I apologize for sending it as a bug report. Subsequently, I will say that there is a bug in the documenation--namely that the documentaion does not contain the specification of how to escape a single ampersand (&).
