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. The search box where you enter your search terms
2. Field chooser - to search within a specific field (Note that All Textis the default option)
3. Search Button
4. Boolean Operator selection - choose AND or OR or NOT to refine your search (there's more about Boolean operators here). Below this you have the option Adding a Row - and a new search term and the field in which it should appear
5. Add additional fields
6. Clear All to start again
