在数据库中搜索整个字符串/短语

Question

I have a form where there are two radio buttons .

One should search for entire string and second one for at least one word from string.

For example:

I will search for " Awesome ideas for startup ".

If I check "Search for entire string / phrase", where it must contain exactly what I typed.

• I want return something like "There where many awesome ideas for startup ".
• Or " Awesome ideas for startup that will blow your mind".

If I check "Search for all words contained".

• I want return something like "This startup is amazing".

I don't have problem with submitting the form or anything like that, but problem with SQL query that will return results which I mentioned above.

if ($_POST['selectedRadio'] == 'entireString') { 
   $query = '/* QUERY HERE */';
} elseif($_POST['selectedRadio'] == 'containedWords') {
   $query = '/* QUERY HERE */';
}

Is there any efficient and fast way to get those wished results?

Thanks.

Answer 1

SELECT * FROM table_name WHERE column_name LIKE %your_string%

This code will search in table exactly what you're looking for, string or phrase. Google for sql like command and build query what you need.

Answer 2

Already solved this problem.

"This startup is amazing". - Managed to return this with Fulltext search.

"There where many awesome ideas for startup". - Managed to return this with LIKE condition.

Thanks for help everybody.

您可以使用（.isSpace）定位分隔每个单词的白色间距，这不是确切的答案，但是您可以从这种方式开始研究。

Answer 4

String str = "your string";
String[] separator = str.split(" ");//this will split string with space " "
String firstword = separator  [0]; // "your"
String secondword = separator [1]; // "string"

whatever you'' put in string.split will be used as divider,splitter
