I am trying to all grab rows of data from a data table, where one word matches a word within the text in my column 'story'. 

Table Structure:

```
post_id | user_id | story
----------------------------------
1       | 1       | Hello World What's up?
2       | 4       | Hello guys!
3       | 7       | Working on shareit.me! 

```

For Example:

I want to grab all of the posts containing the word hello (I am looking for case-insensitive).

How can I do this?

Here is what I have done so far:

```
// this will be the keyword! so use the variable $filter_tag in the query!
$filter_tag= $_GET['tag'];

//query for getting the users' posts containing the select tag 
$query_posts= "SELECT * FROM posts WHERE user_id= '$user_id' ORDER BY post_id 
DESC";

$result_posts= mysqli_query($connect, $query_posts); 

```

Thanks!
