Sitecore Content SDK 2.3: Better Search, Smarter Routing, and Performance Improvements

In This Article
Sitecore has released Content SDK 2.3, bringing a set of improvements aimed at making search experiences more flexible and application development more straightforward.
The latest version introduces two important search capabilities multi-locale search and faceted search along with improvements to routing in the App Router, performance optimizations, and several bug fixes.
For developers building modern Sitecore applications, the release provides more control over how users discover content and how applications handle localized routes.
What's new in Content SDK 2.3?
The biggest focus of this release is search.
With version 2.3, developers can now take advantage of facets and multi-locale search through the @sitecore-content-sdk/search package and its React hooks.
These additions make it easier to build search experiences where users can narrow down results, work across multiple languages or locales, and get more relevant content.

Unlock flexible search, localized routing, and performance improvements with the latest Sitecore Content SDK 2.3 release.
More powerful search with facets
Faceted search is one of the most useful additions in this release.
Instead of simply returning a long list of search results, facets allow users to refine those results based on specific categories or attributes.
For example, an ecommerce or content-heavy website could allow visitors to filter results by:
- Content type
- Category
- Region
- Language
- Product type
- Other indexed attributes
This gives users a much faster way to find what they're looking for.
For developers, it also means more flexibility when designing search interfaces and filtering experiences.

Multi-locale search support
Another major addition is support for multi-locale search.
Websites serving audiences across different languages and regions often need search functionality that understands localized content. Content SDK 2.3 expands the search capabilities available through @sitecore-content-sdk/search and React hooks to better support these scenarios.
This can be particularly useful for global websites where users expect search results to match their selected language or locale.
Instead of treating search as a one-size-fits-all experience, developers have more control over how localized content is discovered and presented.
Improved routing with the App Router
Search isn't the only area receiving attention in this release.
Content SDK 2.3 also introduces a new configuration option that provides more control over locale prefixes in the App Router.
Handling localized URLs can become complicated as applications grow. Developers may need URLs to behave differently depending on the site's localization strategy, market, or routing requirements.
The new configuration option makes this behavior more flexible, giving developers greater control over how locale information appears in application routes.
Performance improvements
Alongside the new functionality, Sitecore has also included performance optimizations in this release.
While these changes may not be as visible as a new search feature, they are important for applications where performance and responsiveness are a priority.
Developers can upgrade to the latest SDK to benefit from these improvements while also taking advantage of the new search and routing capabilities.
Bug fixes and developer experience improvements
Content SDK 2.3 isn't only about new features.
The release also contains various bug fixes and general improvements designed to make the SDK more reliable and easier to work with.
These types of updates are especially valuable for teams maintaining production applications, where stability can be just as important as adding new functionality.

Why this release matters
The combination of advanced search and better routing control makes Content SDK 2.3 a useful update for teams building localized, content-rich applications.
The major improvements can be summarized as:
- Faceted search for more refined and flexible search experiences.
- Multi-locale search for applications serving content across languages and regions.
- React hook support for the latest search capabilities.
- Improved App Router configuration for controlling locale prefixes.
- Performance optimizations for a smoother developer and application experience.
- Bug fixes to improve overall stability.
Final thoughts
Content SDK 2.3 is a practical step forward for developers working with Sitecore's modern application stack.
The new search capabilities give developers more control over how users discover content, while the App Router improvements make localized routing easier to configure. Combined with performance improvements and bug fixes, the release offers a solid set of upgrades without being limited to a single area of the SDK.
If you're building a Sitecore application with multi-language content, advanced filtering, or localized routing, version 2.3 is worth exploring.
