You can combine any advanced syntax into a single search: regression (autism OR autistic) -descriptor:'regression analysis' -descriptor:'regression (statistics)' descriptor:autism.For example, for information on bullying, but not focused by sexual orientation, search bullying -gay.

You can exclude search terms using the - symbol in the same way you would use a + symbol.

For example, +title:regression multivariate hierarchical linear would return only results with the term regression, with the terms multivariate, hierarchical, and linear being optionally searched in all fields.

You can require search terms using the + symbol in front of one or more words or phrases in your search.

For example, (prekindergarten OR kindergarten) AND literacy will return findings with either the term prekindergarten or kindergarten that also contain the word literacy.

You can use AND/OR to limit the search, with parentheses if required.

For example, while source:'higher education' would include results with the source 'Chronicle of Higher Education', the exact search for sourcex:'Higher Education' would only return results with the source 'Higher Education'.

For exact, case-sensitive field searches, you may use: descriptorx, sourcex, locationx, lawx and assessmentx.
