I need an "OR search" capability on my site. Don't seem to have it, after I tested.

Went through the community posts, and it seems that an "advanced search" is yet to be developed. (This is surprising.)

But meanwhile, is there a way for me to modify the current search plugin's code to make the default space character treated as "OR" instead of "AND"? I need this, in order that I can build a categories list that can pick up multiple tags and call them one category.

Thank you for any advice.

Best regards,

Jeff
