Full Text search using oracle regex - sql

Question

I am trying to use regexp_like() in oracle 11g to achieve text search.
for example I have a table called posts where in title column if I have values
'How to create a new post with pictures and videos'
'How to create a new post enter code here'
and if I write a query
select * from posts where regexp_like(title, '.*pictures.*|.*how.*|.*post.*', 'i')
It returns records having both titles where the second value does not have word pictures in it. I know its because I user '|' in the expression.
What I want to achieve is It should return records only if all the words are present in the column in any order. Help me with the regex please

Hope this will help you.
I wrote a plunker in AngularJS. It is just to demonstrate how the regular expression works.

The regular expression you can use is
/^(?=.(pictures))(?=.(post))(?=.*(how))[a-zA-Z ]{1,100}$/
This means pictures, post, how should be there in the given paragraph.
You can adjust the length of the paragrah as per your requirement.
<form role="form" name="myform">
<div>
<div class="col-sm-8">
<input type="text" ng-model="user" name="inputfield" required="true" ng-pattern="/^(?=.*(pictures))(?=.*(post))(?=.*(how))[a-zA-Z ]{1,100}$/">
<span ng-show="myform.inputfield.$dirty && !myform.inputfield.$error.required && myform.inputfield.$error.pattern">
<small class="text-danger">
