我使用以下代码调用Lucene(确切地说是PyLucene):
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,即使我使用queryparser.escape,“AND OR”也会使查询者绊倒.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.

最佳答案 它不只是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")))
