The query syntax has not changed significantly since Lucene 1.3 (it is now 3.5.0). Parsing Queries Queries can be parsed by constructing a QueryParser object and invoking the parse() method. String querystr = args.length > 0 ? args[0] : "lucene"; Query q = new QueryParser(Version.LUCE...

在QueryParser.jj文件中,PARSER_BEGIN(QueryParser)和PARSER_END(QueryParser)之间,定义了QueryParser类。 其中最重要的一个函数是public Query parse(String query)函数,也即我们解析Lucene查询语法的时候调用的函数。 这是一个纯Java代码定义的函数,会直接拷贝到QueryParser.java文件中。 parse函数中,最重要的一行代码是...
You can embed Boolean operators in a query string to improve the precision of a match. The full syntax supports text operators in addition to character operators. Always specify text boolean operators (AND, OR, NOT) in all caps. Text operatorCharacterExampleUsage ...
在Azure AI 搜尋中建立查詢時,您可以針對特殊查詢表單選擇完整的 Lucene 查詢剖析器 語法:通配符、模糊搜尋、鄰近搜尋、正則表示式。 除了透過表達式建構$filter的*range 搜尋之外,Azure AI 搜尋中大部分 Lucene 查詢剖析器語法都完整地實作。若要使用完整的 Lucene 語法,請將 queryType 設定為 full ,並傳入以通配符...

https://lucene.apache.org/core/2_9_4/queryparsersyntax.html 概述里提到QueryParser是通过JavaCC把用户输入的String转换成Query对象,那什么是JavaCC?JavaCC就是一个非常流行的用Java写的解析器生成器。 Before choosing to use the provided Query Parser, please consider the following: ...

OpenSearch supports using Apache Lucene syntax for query_string queries. This is particularly useful for passing multiple filters in a query.
