Unexpected error when a string ends in backslash

[Rob Scott]

I recently ran into a puzzling and unexpected error when doing what seemed like a fairly straightforward LINQ query - no advanced Lucene stuff. Here is a much simplified version of the code - pretty straightforward.

var query = session.Query<ExampleIndex.ReduceResult, ExampleIndex>();

var results =

query.Where( x => x.Query == "thing thing \" )

.As<Example>()

.ToList();

However, since the searchText (1) contains a space and (2) ends in a backslash, this query will throw an exception with the following message:

Lucene.Net.QueryParsers.ParseException: Could not parse: 'Name:\"thing thing \\\"'

---> Lucene.Net.QueryParsers.ParseException: Cannot parse 'Name:\"thing thing \\\"':

Lexical error at line 1, column 21.  Encountered: <EOF> after : \"\\\"thing thing \\\\\\\"\"

---> Lucene.Net.QueryParsers.TokenMgrError: Lexical error at line 1, column 21.

Encountered: <EOF> after : \"\\\"thing thing \\\\\\\"\"\r\n   

If I use RavenQuery.Escape() I can avoid the issue, but I thought that was only necessary for advanced Lucene queries.

Any ideas? Thanks!
