So the Google powered search function is once again working. It stopped working and I am at a lost as to why but I was able to fix it.
It will let the site run without crashing quite so often (the default WordPress search using a very load intensive query that is clearly not meant for sites as large as TGN) and it also now draws in results from the TGN Blog Network as well.
The down-side is that the search results will often have Google ads in them. The more “popular” the search the more likely the chance of ads. Oddly searching for “Frothers” results in paid ads.
