Brackets in query syntax?

Are brackets, [ and ], legal in a query?
If so, do they have some special meaning?
If not, are there other "illegal" characters as well?

Parsing the query syntax, "[]", causes the following error:

Lexical error at line 1, column 3. Encountered: <EOF> after : "[]"
org.apache.lucene.queryParser.TokenMgrError: Lexical error at line 1, column
3. Encountered: <EOF> after : "[]"
at
org.apache.lucene.queryParser.QueryParserTokenManager.getNextToken(Unknown
Source)
at org.apache.lucene.queryParser.QueryParser.jj_ntk(Unknown Source)
at org.apache.lucene.queryParser.QueryParser.Modifiers(Unknown
Source)
at org.apache.lucene.queryParser.QueryParser.Query(Unknown Source)
at org.apache.lucene.queryParser.QueryParser.parse(Unknown Source)
at org.apache.lucene.queryParser.QueryParser.parse(Unknown Source)

I am using QueryParser and the StandardAnalyzer to parse the query string.

Any help would be appreciate.
Paul

[ and ] are used for RangeQuery. They indicate an inclusive range. For
example: "name:[adam-scott]"

Thanks, I didn't see anything about the range query in the syntax BNF.

In regards to the exception, I would expect that searching on the query "[]"
or "name:[]" would either find all documents or no documents, not throw an
exception?

Sure, that would make sense to me...
