Several pages on the CopsModels website use Google's Custom Search Engine (CSE) to search the CoPS website. This displays a search box, into which you can type a query. For some reason, the search box may not be visible, if you are using Internet Explorer (particularly an older version of Internet Explorer).
One remedy may be to install and use a standards-compliant browser, such as Firefox or Chrome.
Or you can use a standard Google searchbox to search ONLY the CopsModels website by entering into the Google searchbox, for example:
which will return all pages at copsmodels.com that mention "Canada".
Sadly, the search box will not be visible in mainland China, where access to Google services is blocked (as of 2015).
