Example if I am searching
"How to enable a google chrome extension only in incognito mode"
It shows results from
"How to enable a google chrome extension in incognito mode"
Obviously this is not what I wanted and I want to emphasize on 'only' Is there any advanced search filter for that.
I did lot of research, and from a webmasters point of you using
<strong><b><em> tag must be used while writing content, i.e., if I am writing a blog about the same topic I must write it like
<h1>How to enable a google chrome extension <em>only</em> in incognito mode</h1>
I don't know how much of it is a fact ergo I need some assistance.
