Summary

The right parenthesis needs a matching left parenthesis.

Workaround

Perform the following:

1. Correct the search syntax by performing one of the following:
   • Close the expression by adding a left parenthesis to the left of the right parenthesis. For example, the expression "a & b)" should be changed to "(a & b)".
   • Remove the right parenthesis. For example, the expression "a & b)" should be changed to "a & b".
2. Perform the search again.
