问题描述
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,不推荐使用此构造函数,并且 new TextField $应该使用c $ c>而不是
new Field
。
However, in Lucene 4.0 this constructor is deprecated and new TextField
should be used instead of new Field
.
但是的问题TextField
是它在构造函数中不接受 TermVector
。
But the problem with TextField
is that it don't accept TermVector
in its constructors.
是否存在使用新构造函数在Lucene 4.0的索引中包含Term Vector的方法?
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是一个方便的用户没有术语向量的索引字段。如果您需要术语向量,只需使用。它需要更多代码行,因为您需要创建首先,将 storeTermVectors
和 tokenizer
设置为true,然后使用此 FieldType
字段
构造函数中的实例。
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.
