Difficulty with user-generated content accuracy

Challenges in representing unique artworks

Existing search system limited for long-tail queries
Redbubble, a global online marketplace known for print-on-demand products, faced challenges with their existing search capabilities. Their platform was mainly powered by user-generated content, making it difficult to accurately represent artwork. The user-generated metadata, such as tags and titles, was prone to inaccuracies and manipulation, which created difficulties in capturing the true essence of the content. With a sophisticated search stack already in place, improving the relevance of search results was challenging, especially for long-tail queries which had sparse interaction signals. Their OpenSearch system worked well for popular queries, but there was room for improvement with more descriptive, three-plus-word queries.
