Log with the exception

Minus sign is not escaped in SOLR translator which causes parse exception, because the "-" is a special character.

Example of query:
Query:

SELECT BQT1.SmallA.IntNum FROM BQT1.SmallA WHERE BQT1.SmallA.IntNum = -1

Query parameter q is set to:

IntNum:-1

but it should be:

IntNum:\-1

Log is in the attachment.
