oracle - 使用 CONTAINS 的 Oracle XML 全文查询，和 INPATH

Question

<query>我正在努力寻找一种使用语法和 INPATH 表达式组合全文查询进程的方法。

给定下一个代码，Oracle 将忽略 INPATH 表达式。

SELECT DISTINCT publication.id, SCORE (1)
   FROM TBL_PUBLICATION publication
   WHERE 
         ( ( (CONTAINS (
                     xmlcontent,
                     '(<query>
                         <textquery grammar="CONTEXT" >my text
                           <progression>    
                             <seq><rewrite>transform((TOKENS, "{", "}", " "))</rewrite></seq>    
                             <seq><rewrite>transform((TOKENS, "{", "}", " NEAR "))</rewrite></seq>    
                             <seq><rewrite>transform((TOKENS, "$(?{", "})", " AND "))</rewrite></seq>
                           </progression>
                         </textquery>
                      </query>) INPATH(//foo/bar)',
                     1) > 0))              
ORDER BY SCORE (1) DESC
