LXR 1.0 and 1.1-beta
When querying for identifier in 'ident', occurrences are not reported if they differ in case from the query key. This is important for case-insensitive languages where the identifier is recorded in uppercase into the database.
Suggested fix: query the database a second time with the identifier folded to uppercase then merge the two lists, eliminating duplicates. To warn user, uppercase matches (i.e. approximate matches) could be flagged with a distinctive character.
