Search form with strange results

I created a frontend search forrm (following @Louis 's tuto) but I get strange results with a CPT.

Test 1
Input: 10
Result: 1 post is selected but nowhere in the post I can find this value (10) even in code.

Test 2
Input: 13
Result: only 1 post is selected but a lot of post containt this value (13).

Environment info

  • WordPress version: 6.1.1
  • Gutenberg Plugin version: N/A
  • Cwicly Plugin version:
  • Cwicly Theme version: 1.0.3

Hi there @weedor,

Thanks for the report and apologies for the inconvenience.

I’m not aware of any particular issue with the search parameter currently as it uses basic WordPress functionalities.

Can you first of all confirm that the filter search input is linked to the search parameter in the Query Editor?

Thanks in advance.
