A search containing an uppercase boolean operator, like foo OR bar, will crash the search portlet when Solr is configured as the search engine and Advanced Search Syntax mode is enabled.

Steps to Reproduce:

1. Set up Solr as the search engine
2. Go to the Search Portlet Configuration > Other Settings > check Use Advanced Search Syntax
3. Search for foo OR bar

Expected Result:
Search would be executed without error

Actual Result:
Search portlet displays "Portlet is temporarily unavailable." error message
