2. Limit to: Full text

Full text is the search limit that appears in the Command Line Search.

Checking the Full text limit will restrict your search to only search and retrieve records containing full text from ProQuest.

NOTE: This limit will only appear if you use ProQuest Dissertations & Theses Full Text and if it has been turned on in the ProQuest Administrator Module. Whether or not this is checked by default is also determined by your ProQuest Administrator Module settings.

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.
