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
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.
