The document discusses keywords and Boolean searching for research projects. It recommends defining keywords by brainstorming related terms from sources like thesauri and content pages. Keywords can be categorized by subject, related terms, broader terms, and synonyms. Boolean operators like AND, OR, and NOT are used to combine keywords and exclude unwanted terms. Phrases should be searched with quotation marks. Truncation and wildcards can help find variant word endings and spellings. Proper citation and referencing of sources is also important.
