问题
Looking at the OpenGrok help page reveals that the search query is based on Lucene, and Lucene in turn indicates that search queries are converted to lower case. I was wondering if there is any way to change this behavior and perform a case-sensitive search.
回答1:
Reference search (-r) is case sensitive, as is definition (-d).
