The index search tab of helponline is case sentitive. "Table" and "table" return different results.
Make it return the same results.
The code is in help.js
To test, one may download the 60.tar.gz and install in a local webserver (230MB)
Instead of downloading the tarball, fix it in Firefox scratchpad and put the patch here.
