PHP SQL搜索查询匹配

I have a search page in PHP which uses the following query to fetch content from the database.

SELECT * FROM linkBase WHERE (`title` LIKE '%".$s."%') OR (`descr` LIKE '%".$s."%')

Here is how my DB looks like :

id  |title         |descr
-----------------------------------------
1   |Hello World   |This is a hello world description
2   |PiedPiper     |The silicon valley company PiedPiper
3   |StackOverflow |Ask questions on programming

Now, for example, if I run this query with the value of $s = "silicon valley", Then it fetches the row 2. This is fine. But what if the user enters the search term as silicon PiedPiper. It returns no results with the above SQL query. How can I modify the query in such a way that it will return row 2 with the second search term too.

Question summery : How can I do a search query using PHP and SQL in such a way that a result will be returned even if the the user enters two words which are not placed consequent to each other in the DB
