Hi,

I’m doing a research of how google filters its keyword query in search box,

e.g number’5 will ignore “’”, and number #5 will ignore “#”

Is there a directory or place where i can find all these chars which will get eliminated from the search query? a syntax of how google handles query will also be fine!

Thanks in advance,  
Mars
