TranslatePress Compatibility Issue

Hello WowStore Team,

I would like to provide an update after further investigation.

We have tested several approaches to determine whether this is a configuration issue or a compatibility issue. Additional Investigation

1. TranslatePress Compatibility Filter

We tested the recommended compatibility filter:

add_filter('trp_force_search', '__return_true');

Unfortunately, this did not resolve the problem. It altered the search behaviour but still did not allow searching by translated Chinese product titles,

so we removed it.

2. WordPress Search Hooks

We also investigated whether the issue could be solved using standard WordPress search hooks such as pre_get_posts or language-related filters.

After tracing the request flow, we found that these hooks are not applied because the WowStore Search Block uses its own custom REST API and custom SQL queries rather than the standard WordPress search mechanism.

3. Source Code Investigation

We inspected the WowStore source code and found that the search query only searches the original WooCommerce fields, including:

• wp_posts.post_title
• wp_posts.post_content
• wp_posts.post_excerpt
• SKU

TranslatePress stores translated product titles in its own translation tables instead of modifying the original WooCommerce product title. As a result, the translated Chinese titles are never included in the search query.

From our investigation, the frontend translations are working correctly, so TranslatePress itself appears to be functioning as expected. Conclusion

Based on our findings, we believe this is a compatibility limitation in the WowStore Search Block rather than a TranslatePress configuration issue.

Could you please help us investigate this further and advise whether:

• this compatibility is currently supported,
• there is an existing workaround,
• or whether the search logic could be enhanced to support translated product titles from TranslatePress?

If needed, we are happy to provide administrator access, debugging information, or assist with additional testing.

Thank you very much for your support. We look forward to your guidance.

Best regards,
