I explained my problem, I bought different search module for CB but none found when searching my checkboxes, for example:
[x] author
[ ] singer
[x] musician
When searching by writing the author, the component never finds that check 'author' for such a musician, so I think we could also automatically populate another text field 'author' automatically (default) when you check the 'author', but I'm a bit lost not knowing how I should do, if you have an idea ...
thanks
