The Advanced Search in Omni makes complex searches possible. By using the Advanced Search, you are considering elements like "Subject Heading", "Resource Type" and "Publication Date" upfront whereas in the Simple Search, you are limiting by them afterwards. A Simple Search allows you to discover everything; an Advanced Search, when well-constructed, helps you find items that fit your predetermined criteria. Take a look below for strategies in using the Advanced Search.
1. What is your Search Scope?
2. Are you interested in a known author or title? Or in a topic?
In Omni, fields can also be combined. If you consider one or two concepts essential to your topic, they can be searched as Subject. The least important topic can be searched as Any Field.
3. What Boolean Operator is necessary for your search statement?
Don't forget to capitalize AND / OR in the search.
4. Do you need an extra row for an additional concept? A third concept will focus your search and also generate fewer but potentially more relevant results.
5. What type of resource is required?
6. English or French may be useful limits.
7. Do you need recent material? Put your cursor next to "Month" and you will see "Year".
If you wanted to find Books available at York, in English, about employment in Canada from a feminist point of view, published between 1970 and 1990, this is what it would look like. Note that Canada is a Subject (countries can be searched as subject so you get materials about them), the concept of work and its synonyms will likely yield results as a Subject. To cast a wider net for items from a feminist point of view, Any Field is used.
