Tips and tricks and general search engine help
Search results are not case sensitive, so HAPPY is the same as happy
which is the same as Happy and so on.
The "rank by relevance of results" search option returns the most relevent
results first and the least relevent ones later. This is the best option
for general purpose searching for a specific topic of interest.
The "Only the most relevant results" search option returns only the most relevent
results, so all the key words in you search querry must match the document, in
order for a result to be returned. This is the better option if you know what
you are looking for.
Certain words are excluded from the search results, these include:
"AND"
"and"
"OR"
"or"
"IF"
"if"
"A"
"a"
"AT"
"at"
"FOR"
"for"
"TO"
"to"
"MY"
"my"
