如何在Lucene 4的搜索中获得多个单词

Question

I'm trying to get a string with Lucene 4. Actually now I'm using SpanTermQuery , but it only is able to get simple words like "Walking", "dog" ..etc. But what I want to do is get more complex as "The dog is walking".

Is there any kind of query which does that?

Answer 1

The "get multiple words" concept is very generic. If you mean that you'd like to get a phrase like "the dog is walking" then you can use A SpanNearQuery specifying slop and in order where:

• slop Is the maximum number of intervening unmatched positions permitted;
• inorder specifies if the matches have to be in order.
