Can anybody help me out on this ..?
I have to search for a particular value over multiple fields and need to
know if grouping is allowed over multiple fields
eg.
<some query> AND ( AUTHOR_NAME:krish OR EMPLOYEE_NAME:krish )
Introducing paranthesis "(" is giving me lexical error
I don't see anything wrong with this, but maybe the query parser doesn't
like it. You could construct it programatically:
1. Use the QueryParser on <some query>
2. Create TermQuerys for AUTHOR_NAME and EMPLOYEE_NAME
3. Construct the necessary BooleanQuery
If it is the query parser and you need free text queries take a look at
the JavaCC source and find the bit that handles nested queries and see
why it doesn't like your field restrictions.
