Question

这是我的表结构：

CREATE TABLE semantified_content_key_word
(
  id bigint NOT NULL,
  semantified_content_id bigint,
  key_word_text text,
  content_date timestamp without time zone NOT NULL,
  context_id bigint NOT NULL,
  CONSTRAINT pk_sckw_id PRIMARY KEY (id )
)
WITH (
  OIDS=FALSE
);
ALTER TABLE semantified_content_key_word
  OWNER TO postgres;


-- Index: idx_sckw_kwt

-- DROP INDEX idx_sckw_kwt;

CREATE INDEX idx_sckw_kwt
  ON semantified_content_key_word
  USING gin
  (to_tsvector('english'::regconfig, key_word_text) );

-- Index: idx_sckw_sc_id

-- DROP INDEX idx_sckw_sc_id;

CREATE INDEX idx_sckw_sc_id
  ON semantified_content_key_word
  USING btree
  (semantified_content_id );

以下是数据：

INSERT INTO semantified_content_key_word (id, semantified_content_id, key_word_text, content_date, context_id) 
      VALUES (7347, 7347, ', agreementnumber customer servicecreditdate the guarantor taken exhausted prior being pursuant avoidance doubt shall remain liable case non incomplete', '2014-11-21 00:00:00', 111);

-------------------------------------------------------------
select sckw.*
FROM semantified_content_key_word sckw
where TO_TSVECTOR(sckw.key_word_text) @@ TO_TSQUERY('exhausted');

这是我正在运行的查询。关键字“耗尽”只出现在其中一行中，但我得到了所有3行。

如何避免关键字不存在的行
