Advanced Search Options
Google Scholar has advanced search options, similar to those in Google's web search engine. However, the advanced options in Google Scholar are geared towards finding scholarly literature based on credentials that are common among research material.
To access the advanced search options, simply click the Advanced Scholar Search link next to the search field. This will bring up a new page with a multitude of search options. At the top of the page you will find a few filtering methods that are common between Google's web search and Google Scholar. You can search by looking for all the words in your search, by exact phrase, with at least one word from your search, and without specific words. You can also determine if your search should be performed anywhere in the article, or just in the title.
To search for a specific author, publication, or within a date range, simply enter your criteria in the corresponding fields. Note that each option on the advanced scholar search page further filters search results.
Next, decide whether you wish to search articles/patents or legal material. Within the articles and patents area, you can search articles in all subject areas or only within specific areas. If you are searching for legal materials, then you can decide to search all legal opinions and journals, federal court opinions, or opinions from any number of states.
