如何使用C# Lambda表达式在MongoDb中执行全文搜索

using MongoDB.Driver;

string connectionString = "mongodb://localhost:27017";

var client = new MongoClient(connectionString);

var database = client.GetDatabase("your_database_name");

var collection = database.GetCollection<BsonDocument>("your_collection_name");

var filter = Builders<BsonDocument>.Filter.Text("your_search_keyword");
var projection = Builders<BsonDocument>.Projection.MetaTextScore("score");
var sort = Builders<BsonDocument>.Sort.MetaTextScore("score");

var searchResults = collection.Find(filter)
                              .Project(projection)
                              .Sort(sort)
                              .ToList();

foreach (var result in searchResults)
{
    // 处理搜索到的文档数据
}
