Lucene QueryParser 将 'AND OR' 解释为命令？

Question

我正在使用以下代码(准确地说是 PyLucene)调用 Lucene:

analyzer = StandardAnalyzer(Version.LUCENE_30)
queryparser = QueryParser(Version.LUCENE_30, "text", analyzer)
query = queryparser.parse(queryparser.escape(querytext))

但请考虑这是否是 querytext 的内容:

querytext = "THE FOOD WAS HONESTLY NOT WORTH THE PRICE. MUCH TOO PRICY WOULD NOT GO BACK AND OR RECOMMEND IT"

在这种情况下，“AND OR”会触发查询解析器，即使我使用的是 queryparser.escape .如何避免以下错误消息？

    Java stacktrace:
org.apache.lucene.queryParser.ParseException: Cannot parse 'THE FOOD WAS HONESTLY NOT WORTH THE PRICE. MUCH TOO PRICY WOULD NOT GO BACK AND OR RECOMMEND IT': Encountered " <OR> "OR "" at line 1, column 80.

不仅仅是OR ，它是 AND OR .

我使用以下解决方法:

query = queryparser.parse(queryparser.escape(querytext.replace("AND OR", "AND or")))
