Problem using full-text search

Per the forum discussion, attempting to execute a full-text search produces an error. From the user:

It works fine if I use language as JCR-SQL2 and type a query like "select * from [nt:file] where 'jcr:createdBy'='Fred'". However, if I use language Search for full text search with an expression of 'Fred', it failed with the following error:

There has been an error processing your command

I tried using different sources (JPA Source, Filesystem Source) and received the same error.
