Lucene Query的extractTerms的替代方法是什么? [英] What is an alternative for Lucene Query's extractTerms?

问题描述

在Lucene 4.6.0中，有extractTerms方法提供了从查询中提取术语的方法(查询Lucene 6.2.1 ).是否有有效的替代方法?

In Lucene 4.6.0 there was the method extractTerms that provided the extraction of terms from a query (Query 4.6.0). However, from Lucene 6.2.1, it does no longer exist (Query Lucene 6.2.1). Is there a valid alternative for it?

我需要解析由QueryParser构建的查询的术语(和对应字段).

What I'd need is to parse terms (and corrispondent fields) of a Query built by QueryParser.

推荐答案

也许不是最好的答案，但是一种方法是使用相同的分析器并标记查询字符串:

Maybe not the best answer but one way is to use the same analyzer and tokenize the query string:

Analyzer anal = new StandardAnalyzer();
TokenStream ts = anal.tokenStream("title", query); // string query
CharTermAttribute termAtt = ts.addAttribute(CharTermAttribute.class);
ts.reset();
while (ts.incrementToken()) {
    System.out.println(termAtt.toString());
}
anal.close();
