MongoDB:Combineer Tekst Zoeken en Geospatial Query

Mongo DB zelf ondersteunt niet tegelijkertijd zoeken op tekst en geografisch gebied.Zie dit

Maar u kunt de zoekopdracht combineren en het resultaat bereiken

Oplossingen

1. regex + in de buurt

const aggregate=YourCollection.aggregation()
aggregate.near({
    near:coord,
    includeLocs: "loc",
    distanceField: "distance",
    maxDistance: distance
});
aggregate.match({name:{$regex:keyword,$options: 'i'}})
aggregate.exec(function(err,yourDocuments){
    //your smart code
}) 

2. Tekst zoeken + regex

   var aggregate=YourCollection.aggregate();
   var match= {
     latitude: { $lt: yourCurrentLatitude+maxDistance, $gt: yourCurrentLatitude-maxDistance },
     longitude: { $lt: yourCurrentLongitude+maxDistance, $gt: yourCurrentLongitude-maxDistance },
     {$text:{$search:keyword}}
   };
   
   aggregate.match(match).exec(function(err,yourDocuments){//your smart code})
   

3. Mapreduce + ( Tekst zoeken Of regex )

YourCollection.mapReduce(map, reduce, {out: {inline:1, query : yourFirstQuery}}, function(err, yourNewCollection) {
// Mapreduce returns the temporary collection with the results
    collection.find(yourNewQuery, function(err, result) {
      //your awsome code
    });
});
