Im在Skite FTS3虚拟表格中储存指数的应用。 我们正在执行全文,即意味着我们通过诸如:
select * from blah where term match <insert term here>
直到我们想要匹配的词句中含有一个hy子,把ba子解释为ba,而不是鸡蛋。
是否有任何人知道有越狱的性质,使 f子忽略了phen子? 我尝试添加一个亚太经社会的E条款,并在每条hy字之前使用,但对应声明反对这一辛迪加。
感谢。

很多人认为“特殊”需要逃脱。 这样做的最容易的方法是,在你希望寻求的周围添加DOUBLE。
bacon-and-eggs
。
select * from blah where term match "bacon-and-eggs"
这还把整个扼杀视为一种短语,因此,用同样的话打上不同的顺序,不会造成任何打击。 逐字逐句。
<><>Example 2 请检索的术语为bacon和eggs
。
select * from blah where term match "bacon" "and" "eggs"
希望能帮助人们!
这个问题是老的,涉及,但我认为,我还要补充一份最新情况,以表明你如何利用新手fts5。
首先,在指挥线上建立试验环境:
$ sqlite3 ":memory:"
然后建立一个能够处理干 the的5号桌子:
sqlite> CREATE VIRTUAL TABLE IF NOT EXISTS blah USING fts5(term, tokenize="unicode61 tokenchars - ");
通知在<条码>标注条码>值中以微妙方式使用双字母和单一字母。
在确定方式后,请加上一些价值观,以寻求:
sqlite> INSERT INTO blah (term) VALUES ( bacon-and-eggs );
sqlite> INSERT INTO blah (term) VALUES ( bacon );
sqlite> INSERT INTO blah (term) VALUES ( eggs );
然后,请他们实际搜寻:
sqlite> SELECT * from blah WHERE term MATCH "bacon-and-eggs" ;
bacon-and-eggs
sqlite> SELECT * from blah WHERE term MATCH "bacon"* ;
bacon-and-eggs
bacon
我们再次注意到搜索术语使用双字母和单一报价的微妙之处。
服贸总协定忽略了指数中所有非字母数字特征。 在向商品交易所发送搜索词之前,你可以将其改为
bacon NEAR/0 AND NEAR/0 eggs
