The advanced search function is very powerful. You can use it to create structured queries, where you apply limiters before searching instead of after. Like the search results page, it can look a bit complicated. Let's break it down.

1. Advanced Search Options Menu. These are:
   • Command Line Search. Use this to build a customised search using a combination of search terms, Boolean Operators and specific searchable fields
   • Recent Searches - access your recent searches and chooses to re-run them
   • Thesaurus. Many ProQuest databases have an associated thesaurus (also called a controlled vocabulary of subject terms). Using these thesauri, editors assign one or more terms from an approved list to each item to describe their content and make them then easier to find when you're searching. With a thesaurus opened, you can browse terms, or select one or more to add to your search
   • Field Codes. The item records in British Nursing Database are very well-organised, each unique bit of information in a record is organised into fields (such as title, author, abstract etc). This is a list of field codes that you can use to identify the different fields in records
   • Search Tips - opens a pop-up box with some more information about how to search efficiently and effectively
2. The search box where you enter your search terms
3. Field code chooser - to search within a specific field (Note that Anywhere is the default option)
4. Boolean Operator selection - choose AND or OR or NOT to refine your search (there's more about Boolean operators here)
5. Add a Row - and a new search term and the field in which it should appear
6. Limit to full-text and/or peer reviewed material
7. Limit by publication date
8. Choose source type
9. Choose document type
10. Choose language

8-10 are the same options that appear as limiters on the search results page, it's just that on the advanced search you get to limit the results before you search.

There are also Result page options - below the search limiters:
