The Caspio Low-Code Platform
All the Tools and Support You Need
Unlimited Users With Every Plan
October 24, 2011
If you are working with online database apps, chances are that you have already made or are thinking about creating a search form for users to quickly find the data they are looking for. We have gathered a short list of best practices that can make your search form much easier to use.
The smaller the search form, the fewer things the user has to think about and therefore the easier it is to use. Can you get away with just one field or a few fields? If some users need more advanced filtering options, you can set up a secondary “Advanced Search” interface and link to it.
The less text you have on your search form, the easier it is on the eye. If you need to explain an option, do it below the field rather than on the label.
If at all possible, provide default values in your fields. For dropdowns, always include “All” or “Any” and make it the default.
Organize your search form in such a way that the fields most people use are at the top and the less frequently-used fields are at the bottom of the form.
Are any of your search fields vague or unclear? For example, if you have a set of “From/To” date fields, is it clear whether search results are inclusive or exclusive of the date values? A small textual tip could make it clearer.
You may have little choice on this, but to the extent possible try to keep dropdown choices below 10The upcoming release of Caspio 7.2 includes a new form element called AutoComplete offering a great alternative to heavy dropdowns. It works similar to a Google search box where as the user types search keywords, a matching selection of choices are shown from the associated lookup table.
Give your users the ability to share their improvement ideas with you. Provide a link to a feedback form on your page.
Usability is part science and part art; however it is highly dependent on the audience that your app serves. The general public has a completely different standard for usability than a team of research scientists.
