Database records consist of fields that contain specific pieces of bibliographic information.
Common fields include:
Most databases will default to searching in all the main fields (see Database Platforms below), but changing this to search only in a specific field, or fields, can give you more precise results.
For topic searching, it's a good idea to search in the Subject field, but searching in the Title field can work quite well too. If you are searching for an author, you can search only in the Author field; if you are searching for a publication, you can search only in the Publication (also known as the Source) field.
To find the various fields in which you can search, look for drop-down boxes or menus. Here's the EBSCOhost Advanced Search screen.
You can combine search terms, search operators, and field searching to build quite complex searches, and get precise results:
For information on searching using a thesaurus, see Using a thesaurus.
So far, we have looked at how search operators, truncation, keyword- and phrase-searching, and field searching can narrow or broaden your search.
Search limiters are another important way to narrow a search, and most databases offer a range of limiters that you can use as part of your search, or that you can apply after you have your results. In the latter case, they are usually called refiners or filters, because they refine/filter your results.
Common limiters include:
Other limiters will be available according to the subject content of the database, but might include:
To find limiters to add to your search, look for tick-boxes and drop-down menus on the main search page. To find refiners to refine your results, look for lists to the left or right of your results list:
EBSCOhost is a platform for about 30 databases covering most of the subjects taught at CSU. It includes a number of subject-specific databases, plus the multi-subject database Academic Search Complete.
In EBSCOhost, you can change from one database to another, or select multiple databases, by clicking on Choose Databases above the search boxes.
When you go to an EBSCOhost database, you should be in the Advanced Search screen.
EBSCOhost defaults to a keyword-search. If you type in ... tertiary education, this will search for tertiary AND education. To search for the phrase tertiary education, you need to enclose the words in double quotation marks ... "tertiary education".
The field(s) to be searched defaults to Select a Field (optional). This includes the main fields in the records. This varies from database to database but usually includes author, title, subject/keywords, and abstract. To specify a field to be searched, use the drop-down menu.
EBSCOhost defaults to sorting results by Relevance.
To see more information about each item, click on the Preview button to the right of the record. To add it into a folder, click on the Add to Folder button beside the Preview button.
To see the full record, and access various tools, click on the title of the item.
CSU Library has put together a series of subject packages of EBSCOhost databases including:
ProQuest is a platform for nearly 100 databases covering most of the subjects taught at CSU. The database menu is organised in a hierarchical structure, with many of the top-level databases consisting of subsidiary databases.
When you go to a ProQuest database, you should be able to select a package of similar (subject-related) databases from the breadcrumb trail at the top:
To access the full menu of databases, click on All databases, and then click on Databases (8). (The "8" refers to the number of top-level databases in our ProQuest subscription.)
When you go to a ProQuest database, you should get the Advanced Search screen.
ProQuest defaults to a keyword-search. This means that if you wish to search for the keyword <tertiary> and the keyword <education>, you should type in tertiary education. If you wish to search for the specific phrase <tertiary education>, you should type in "tertiary education".
ProQuest defaults to searching in Anywhere. This includes searching in the full-text of articles, so, to get more precise results, change this to Anywhere except full-text - ALL.
ProQuest defaults to sorting your results by Relevance.
To see, and go back to, the results of previous searches, click on the Selected Items and Recent Searches button in the top right corner of the screen:
Informit is a platform for nearly 100 databases which have mainly Australian content. But only some of the databases contain full-text content: many are simply indexes. On the other hand, the databases with "Collection" in the title are entirely full-text.
To change from one database to another, or to select multiple databases, click on Change Databases above the search boxes. You can select databases by title, by full-text content, or by subject.
When you go to an Informit database, you should be in the Advanced Search screen.
In Advanced Search, you can specify the field(s) to be searched, and whether your search will be a keyword-search (All terms) or a phrase-search (Exact phrase). You can also specify that your search terms are combined with the OR operator (Any terms).
Informit defaults to sorting your results by Date (newest first). You can change this to Relevance.
To see, and go back to the results of, previous searches, click on the Search History link in the black bar across the top of the screen.
Ovid is a platform with lots of databases and with subject strengths in health and medicine, nursing, psychology, and earth sciences. It includes the databases MEDLINE, a number of EBM Reviews databases, PsycINFO, and CAB Abstracts.
In Ovid, you can change from one database to another, or select multiple databases from the menu, by clicking on Change in the Search panel.
When you go to an Ovid database, you should be in the Advanced Search screen. There are other search modes, including Basic Search, where you can enter your topic in pretty much whatever words you like, and where your results will be tagged and sorted by relevance.
In Advanced Search, Ovid defaults to a phrase search. If you wish to search for the keyword <brain> and the keyword <injury>, you should type in brain AND injury. If you wish to search for the specific phrase <brain injury>, you can type in just brain injury (without quotation marks).
Search History. Ovid always displays your previous searches in a table above the search box. If you can't see all of your previous searches, click on the Expand link at the top right of this table.
