如何使用 TermVector Lucene 4.0
在索引方法中，我使用以下行:
In the indexing method I use the following line:
Field contentsField = new Field("contents", new FileReader(f), Field.TermVector.YES);
但是，在 Lucene 4.0 中，此构造函数已被弃用，应使用 new TextField 代替 new Field.
However, in Lucene 4.0 this constructor is deprecated and new TextField should be used instead of new Field.
但 TextField 的问题在于它的构造函数中不接受 TermVector.
But the problem with TextField is that it don't accept TermVector in its constructors.
有没有办法使用新的构造函数在我的 Lucene 4.0 索引中包含术语向量?
Is there a way to include the Term Vector in my indexing in Lucene 4.0 with the new constructors?
谢谢
推荐答案
TextField 是一个方便的类，适用于需要没有术语向量的索引字段的用户.如果您需要术语向量，只需使用 字段.由于您需要创建 FieldType 首先，将 storeTermVectors 和 tokenizer 设置为 true，然后在 中使用这个 构造函数.FieldType 实例>字段
TextField is a convenience class for users who need indexed fields without term vectors. If you need terms vectors, just use a Field. It takes a few more lines of code since you need to create an instance of FieldType first, set storeTermVectors and tokenizer to true and then use this FieldType instance in Field constructor.
