It's possible to search for exact words and sentences by using double quotes, e.g. "statistical analysis".

The * wildcard can be used to match partial words, e.g. searching for epigr* will match 'epigraph', 'epigraphy', 'epigraphic' etc.

The - symbol placed before a word will exclude it from the search, e.g. data -processing will match all results that contain 'data' but not 'processing'.
