2. Limit to: Full text, Peer reviewed, Scholarly journals
Full text, Peer reviewed, and Scholarly journals are the search limits that are available in the Command Line Search. The visibility of these limits is determined by your ProQuest Administrator Module settings. Whether or not any of these are checked by default is also determined by your ProQuest Administrator Module settings.
Checking the Full text limit will restrict your search to only search and retrieve records containing full text from ProQuest.
Checking the Peer reviewed limit will restrict your search to only search and retrieve records that are indexed in peer reviewed journals. Peer reviewed journals are a subset of scholarly journals and are defined as journals that undergo a review process where other experts (peers) in the field review the work before it is published in the journal. Peer reviewed journals are also commonly known as refereed journals.
Checking the Scholarly journals limit will restrict your search to only search and retrieve records that are indexed in scholarly journals. Scholarly journals are journals that are intended for an academically oriented audience.
3. Date Range
The Date range limit defaults to search all dates. Other options include Last 7 days, Last 30 days, Last 3 months, Last 12 months, Last 3 years, On this date, After this date, Before this date, and Specific date range.
4. Display Options
The Sort results by menu controls the sort order of the records that appear in the results page. Sort by relevance, date (oldest first), or date (most recent first). Relevance is determined by an algorithm that factors in the number of times your search terms appear in the record as well where in the record your search terms appear.
Items per page is used to select how many results will display on the results page. Choose from 10, 20, 50, or 100 items.
Duplicates can appear in ProQuest if the item is indexed in more than one database or collection. The default behavior is to suppress the duplicate, however, if you would like the duplicate items to appear in the results, select to include duplicate documents.
The ProQuest Thesaurus is used to index the ABI/INFORM subject field. The subject terms are found in the subject field and this is one of the searchable fields listed in the searchable fields table. The thesaurus allows you to find subject terms to narrow or broaden your search. Subjects are also commonly known as descriptors, controlled vocabulary, and sometimes classification terms. In ABI/INFORM, there are different subject types and in addition to the all encompassing subject field, there is also company/organization, person, and location.
For additional details on how to use the thesaurus and search using the subject field, please see the Searchable Fields section of this guide.
