Part of the I2E Enterprise installation is the Sample Web GUI — a Smart Query interface written as a web application that allows users to run smart queries using only their browser.
A neat trick that it performs is on-the-fly class matching: start typing in a word and the server starts to suggest terms in your dictionary that would match. So a search for “psor” will suggest Psoriasis, Psoriatic Arthritis, etc.
Accepting the suggestion will then populate the search with that class rather than the word. The autosuggestion, dropdowns and tooltips are very nice from the user experience perspective, but today’s post will concentrate on the class match itself – how can a search for “psoriasis” retrieve a class match?
There is a two-part answer to that question – the first part is quite easy to answer and the second part is (only slightly) more complicated. So, let’s start with the first part.
Using the query parameters “search”, “pt” or “synonym”
Class matching is a synchronous operation in I2E that uses a query parameter to specify the input and returns the matches as a list/array of classes. Because of this, it’s something that you can try very simply with your web browser. The general form of the URL is (omitting the protocol, servername and port information for brevity):
