通过REGEXP在mysql中搜索时遇到问题

I am implementing search in my project so I have to search data which will be in any order so I'm following this question. But my query was not working

my php query is

 $cat="(?=.*Women)(?=.*Rings)";
 $sql="select * from tbl_jewellery where categories RLike '$cat';";

when I change regex to Women.*Ring|Ring.*Women It works fine but (?=.*Women)(?=.*Rings) approach is easy and can be used for multiple words just adding them.

    MySQL does not implement (? syntax in REGEXPs. I think MariaDB 10.0.5 does.

    For a significant subset of such queries, you could use a FULLTEXT index on that categories with this:

    MATCH(categories)
        AGAINST('+women +rings' IN BOOLEAN MODE)
    

    That says both "words" occur, without limitations on order or proximity.
