intitle: and allintitle: allows you to
search for terms in the page’s titles. Google
is not restricted to
search only the content but can also search the titles of the
pages.
Titles usually describe the purpose of the content and a search in
titles
offers you refined list of results whose contents are more close
to what you’re
looking for. For example: “intitle:india” shows only the results having ‘India’ in
their titles; and “allinurl:india drought crisis” shows only the results having
‘India’, ‘drought’ and ‘crisis’ in their titles.
