Release Highlights

[JSUI-2112] Customize the No Results Message

The QuerySummary component now has several new options which allow you to customize the message to display in a search page when a query yields no results.

You can specify a custom message as a simple string through the component markup (see the noResultsFoundMessage and enableNoResultsFoundMessage options), and/or use custom HTML (by including it inside an element with the coveo-show-if-no-results class).

The upcoming JavaScript Interface Editor release will leverage these enhancements to allow easier No results message customization.

[JSUI-2124/2166/2169/2199] WCAG 2.0 AA Compliance

Many internal changes were made to various component to ensure they are usable by people with vision impairment or other disabilities. Visually, subtle color changes will be noticeable, especially for all clickable elements (e.g., ResultLink components).

You may also want to add ARIA landmarks to your search page to make it even more accessible (see Adding ARIA Landmarks).

[JSUI-2153] Exponential Backoff Mechanism

This enhancement is aimed at improving end-user experience in some corner-case situations where the Search API would rightfully throttle very fast, successive search requests. Rather than eventually responding with 429 Too Many Requests (i.e., Oops, something went wrong), those queries will now typically respond successfully (though somewhat slower).
