Fixing Spring Boot Hotel Search: A Case-Insensitive Solution

When developing a Spring Boot application that interacts with a database, you can run into unexpected issues, especially with search functionalities. One common problem arises when trying to retrieve data based on user input — in this case, hotel names. If you've been encountering trouble with your hotel search function that only returns partial results based on initial characters, you're not alone.

Understanding the Problem

Imagine the scenario:

You have a search function where users can type in a hotel name.

Users expect to find results that match what they are typing; however, they notice that searching for "Sigiriya" by entering "s" works, but anything beyond that, such as "igiriya", returns no results.

This is a frustrating experience for users and can hinder their ability to discover available options. The underlying problem generally lies in how the search logic interacts with the data in the database.

What's Going Wrong?

The original search function might look something like this:

In the above code:

The search string is converted to lowercase.

However, using findAllByHotelNameContentLike generally leads to case sensitivity issues, especially if the hotel names in your database are stored with capital letters.

The Solution: Adopting Case-Insensitive Search

To ensure your search functionality becomes more robust, you can modify the method to perform a case-insensitive search instead. This change will help your application return the expected results regardless of how the user types the hotel names (i.e., uppercase or lowercase).

Updated Code Implementation

Here’s how you can update your existing method to utilize case-insensitive searches:

Key Changes Explained

Using IgnoreCase:

By implementing IgnoreCase, you instruct the database to disregard letter casing when performing the search, leading to a more flexible user experience.

Adding Containing:

The use of Containing allows you to match any part of the hotel name with the provided search key. This means input like "igiriya" will successfully return results for "Sigiriya".

Benefits of the Solution

Improved User Experience: Users can find what they are looking for with more natural typing habits, especially when names might be forgotten or partially remembered.

Increased Efficiency: The search becomes significantly more forgiving of user input errors, reducing frustration and improving broadly the overall system’s usability.

Conclusion

By modifying your Spring Boot search functionality to implement case-insensitive queries, you not only enhance user satisfaction but also make your application more adaptable to various user interactions. This simple fix can dramatically improve how users engage with your hotel search feature.

For developers facing similar issues, remember to always consider that databases might store data in various cases. Embracing a case-insensitive search can save you from a lot of headaches!
