Many of you know that we have come to a plan that reshapes us down to the low 300 's - let 's just say 300 , plus or minus - but 300 is a good round number . It also allows the use of parentheses to help define a search , quotation marks to search exact phrases , < and > to decrease or increase the term 's importance in the search , * ( the asterisk ' wildcard ' ) to match the root of a word , and + and - marks at the start of words to either require the word or exclude pages with the word . So back off everything they supply themselves - the , and , that , would , if , or but - and you 'll have a naturally easy flow to your words . In this way , we obtained a total of 293 surveys completed by graduate students registered in 1992 , with a confidence level of 95 % and a reliability interval of + or – 6 % . The ROM estimate is consider to have + or – 50 % accuracy range . In this mode , the following operators can be employed in order to fine-tune the search process :( no operator ) : By default ( when neither + nor - are specified ) , the word is optional , but the rows that contain it are rated higher . This represents approximately 1.9 % of all undergraduate students registered in 1992 , with a confidence level of 95 % and a reliability interval of + or – 5 % . Working within a time period of 38,000 years , the erosion of this gorge by the Santiago-Verde was accomplished in a period of approximately 5000 years plus or minus - a remarkably short time . The southernmost stone over the wainscot is dressed very flat and true , but rough , + or – .03 . Disease notifications above or below the 5-year mean , plus - or minus - two standard deviations are marked with an asterisk . It virtually declares in these words a third A which is neither + nor - , and which at the same time is yet invested with + and - characters . Why Bill Benson had to bother , trudging all over the country , to collect those , what , 17,000 , plus or minus - - probably plus , probably a low estimate - - 17,000 certified pages of public records . They are estimates consider to have a " + or – 20 % " accuracy .
