      Most databases do not index varchar() fields in a way that is friendly to case-insensitive lookups. There are per-database solutions to this (function indexes in Oracle, generated columns in DB2, etc), but no easy general solution. Since one of the most frequent lookups we do is matched against the lower(title) column of the CONTENT table, we should store a pre-lowercased value of content titles in the database and look up against that instead.

            Thank you for raising this issue. While I can see how this feature would be useful, we have no plans to implement it in the foreseeable future. In order to set expectations, we're closing this request now. Thanks again for your idea.

            I'm attaching a starting point patch which I partially tested before reverting to a less verbose but mysql-specific fix via case-insensitive collation.
