所以, 我發現,查詢的輸出是完美的根據停止詞列表那是在oracle中。
那些話可以在CTXSYS包中找到,並且可以查詢使用
SELECT * FROM CTX_STOPLISTS;
SELECT * FROM ctx_stopwords;
,是的,甲骨文考慮「你」,「會」在您的查詢的非索引字表和停用詞停止的話。 以下列表是默認停用詞。
a did in only then where
all do into onto there whether
almost does is or therefore which
also either it our these while
although for its ours they who
an from just s this whose
and had ll shall those why
any has me she though will

,如果你需要刪除一些指定的字(或添加停止的話),
(你需要** GRANT EXECUTE ON CTXSYS.CTX_DDL給你**) 然後,在你執行一個程序, 例如:
begin
ctx_ddl.remove_stopword('mystop_list','some');
ctx_ddl.remove_stopword('mystop_list','you');
end;
參考link各種功能CTX_DDL包
你可以得到充分DESCRIPT離子有關通過查詢創建的CTX指數,
select ctx_report.describe_index('yourindex_name') from dual;
的
