Notice that we convert the search string to lowercase before commencing. We
do this to make the search case-insensitive. We use the JString class to convert the

and corruption of the query.

Summary
We have explored the massive joomla.html library that enables us to create
standardized XHTML for rendering in our extensions. It??™s important to explore the
library so as to gain as much from it as possible. There are many useful types that
can massively reduce our over all development time.
Investigating the use of existing layouts and templates should put us in good stead

makes it easier for site template developers and ensures that our layouts will not
look out of place.
