** JSON indexes for autocomplete
It will do the autocomplete for the filed name - "roleName"

// this is on the mongodb atlas

{
  "mappings": {
    "dynamic": false,
    "fields": {
      "roleName": [
        {
          "foldDiacritics": false,
          "maxGrams": 7,
          "minGrams": 3,
          "tokenization": "edgeGram",
          "type": "autocomplete"
        }
      ]
    }
  }
}

• How the code will look like if we implement the think into the code for any route

exports.autoComplete = async(req,res,next)=>{
  try{

    let result = [];
    results = await Job.aggregate([
      {
        '$search': {
          'index': 'autoComplete', 
          'autocomplete': {
            'query': req.params.autocomplete, 
            'path': "roleName",
            "tokenOrder":"sequential"
          }
        }
      }, {
        '$limit': 10
      }, {
        '$project': {
          'roleName': 1,
        }
      }
    ])
    
    res.status(200).json({
      status:"success",
      data : {results}
    })

  }catch(err){
    res.status(404).json({
      status:"Failed",
      data:{
        err:err.message
      }
    })
  }
}

for the search field it will look like this

exports.searchField = async(req,res,next)=>{
  try{
    console.log(req.params.search);
    console.log(req.query.name);
    let results = [];
     results = await Job.aggregate([
      { $search: {
          index: 'default',
          text: {
            query: req.params.search,
            path:["companyname","roleName"],
            // path:{
            //   wildcard:"*"
            // },
            fuzzy:{}
          }
        }
      }
    ]);
    console.log(results);

    res.status(200).json({
      data : {results}
    })

  }catch(err){
    
    res.status(404).json({
      status:"Failed",
      data:{
        err:err.message
      }
    })

  }
}
