使用 Java 为 MongoDB 中的外部值分配权重

这就是我如何创建具有不同权重的索引蒙戈外壳.

             db.blog.ensureIndex(
                 {
                   content: "text",
                   keywords: "text",
                   about: "text"
                 },
                 {
                   weights: {
                              content: 10,
                              keywords: 5,
                            },
                   name: "TextIndex"
                 }
               )

这就是我使用以下方法为字段创建索引的方法Java.

    BasicDBObject index = new BasicDBObject();
        index.put("content", "text");
        index.put("keywords", "text");
        index.put("about", "text");

collection.ensureIndex( index, "TextIndex");

如何使用分配权重Java driver?

为索引字段分配权重Java:

    BasicDBObject index = new BasicDBObject();
    index.put("content", "text");
    index.put("keywords", "text");
    index.put("about", "text");
    BasicDBObject weights = new BasicDBObject("content", 10).append("keyword", 5);
    BasicDBObject options = new BasicDBObject("weights", weights).append("name", "TextIndex");
    collection.createIndex(index,options);
