How to perform a $match with $or inside $switch statement in Mongo

Question

Hi I am trying to get multiple searches inside switch so i want to do if one of the following user:search_data||com:search_data||fruit:serch_data matches return search results. i want to do,

$match:{
          $or:[{ user:{$regex:"search_data"}},
          {com:{$regex:"search_data"}},
          {fruit:{$elemMatch: {name:{$regex:"search_data"}}}}
}

this is a search if user it should search user, if com it should search company I have able to do that now i want when we gives all if search data exits on user OR Com OR fruit it should return the search results

   {
            $match: {
              $expr: {
                $switch: {
                  branches: [
                    {
                      case: {
                        $eq: ['$search', 'all']
                      },
                      then: {
                       
                       //to this
                      }
                    },
                 ],
                 default: {}
              }
            }
          }

sample data

 user:"rithuwa",
  com:"abc",
  fruit:[{name:"mango",des:"aaaaa"},{name:"mango",des:"nnnn"}]

sample input

search_data:"rit"---->since this is in user it should output the record
search_data:"mango"--->since it in the fruit.name it should output the record
search_data:"ab"---->since it in the com it should output the record
search_data:"me"---->since it not in user,com or fruit should not give search record
