Hello!
You are mistaken that simple translate the blanks into 'AND' will be good
decision.
Lexical analyzer should take care about quotes, brackets and a lot of reserved
words (e.g. two running AND's are fault)
Small example:
aaa bbb ccc "eee fff" = = AND bbb AND ccc AND "eee fff" but
aaa bbb ccc "eee fff" != aaa AND bbb AND ccc AND "eee AND fff"
