1.Some basics

Some basic aspects about Google

1. Google is case insensitive
2. Google accepts maximum of 32 key words for searching. If you give more than 32 keywords Google will simply ignore it.
3. Some common words like "is", "a", "are" are ignored by Google.
4. The wild card character in Google is '*'. This can be used only for a full word. And this is not included in the word limit. There is no wild card character for a single letter or postfix or prefix for a single word.
5. Logical operators can be used for searching.
6. The logical operators are AND, OR and NOT.
   
7. Not like our maths all the logical operators are having the same preference.
8. OR search includes results for either this or that (one OR two). This can be replaced with '|' one | two)
9. AND returns result having both the key terms (one AND two)
10. NOT operation is performed with the operator '-'. This filters the pages having the word after '-' from the result for the searched term. For example, the search for one -two returns all the pages containing one and not having two.
