Searching can be as simple as entering a few keywords or phrases (e.g. pathology table rats benzene). The search engine finds as many documents containing as many of the words and phrases listed.
However, when the results are numerous, using logical operators in your search query refines your search results. Here are some quick tips to refine your search
|Pathology +table||Pages containing the words Pathology and table|
|Pathology -table||Pathology pages that exclude the word table|
|TR-10*||TR-10, TR-10a, TR-1029 etc.|
|"Pathology table"||Matches the exact wording and spacing; would not match tables of pathology|
