The search function supports the following operators:
A leading plus sign indicates that this word must be present in each row that is returned.
A leading minus sign indicates that this word must not be present in any of the rows that are returned.
By default (when neither a leading +/- is specified) the word catagory results will be present with the results of the word included at the top.
A leading tilde acts as a negation operator, causing the word's contribution to the row's relevance to be negative.
The asterisk serves as the truncation operator. Unlike the other operators, it should be appended to the word to be affected. Words match if they begin with the word preceding the * operator.
A phrase that is enclosed within double quote (“"”) characters matches only rows that contain the phrase literally, as it was typed.
The following examples demonstrate some search strings that use these operators:
Find rows that contain at least one of the two words twin or adult
Find rows that contain both words twin and junior
Find rows that contain the word “twin”, but rank rows higher if they also contain “male”.
Find rows that contain the word “twin” but not “male”.
Find rows that contain the word “twin”, but if the row also contains the word “male”, rate it lower than if row does not.
Find rows that contain words such as “genes”, “genetic”, or “genetics”.
Find rows that contain the exact phrase “molecular genetics”
