š Help me test EPiCās new Commercial EPC FAQ search.
Iāve recently been rebuilding the EPiC Surveys website, gradually updating both its appearance and the information it provides. As part of that wider work, Iāve created a completely new FAQ section designed to provide straightforward answers to many of the questions people ask about commercial Energy Performance Certificates.
Rather than simply presenting a long list of questions, the page includes a search facility. You can type a question in ordinary language, and it will try to identify the most relevant answers.
I deliberately decided not to use artificial intelligence to operate the search. Doing so would raise questions about how visitorsā searches were processed, transmitted and stored. Addressing those privacy and data-handling concerns properly could become complicated and potentially expensive for a small business like ours.
Instead, the search works entirely through a large set of rules that I have provided. These rules help it recognise different words, phrases and ways of asking what is essentially the same question. It works fairly wellābut it isnāt perfect.
The difficult part is no longer fixing the problems I know about. It is finding the searches and unusual ways of phrasing questions that I havenāt thought of. Having spent so much time developing and testing it, Iām probably now too familiar with how it works to uncover every weakness without help.
That is where I would really appreciate some help.
Please visit the FAQ page and try the search facility to destruction. Ask sensible questions, vague questions, badly worded questions, incomplete questions or the same question in several completely different ways. Try anything you think might confuse it.
If the search gives you the wrong answers, fails to find something that ought to be there, or behaves unexpectedly, please use the Report a search issue feature on the page itself. That will give me the information I need to investigate the search and, where necessary, write some new rules.
You do not need to know anything about EPCs to help. In fact, testing by people who do not already know the terminology may be particularly valuable.

Thank youāand please donāt be gentle with it. The more ways you can find to break it now, the better it should work for everyone who uses it.
