====== Mystic Help ====== ===== Advanced Search ===== The **[Advanced Search]** option allows readers to perform specific searches on the database in a more targeted fashion than the general search feature. {{ :pergamonmystic:linkedhelp:mystichelp_opac_0011.jpg?direct&600 |}} Initially, the **Advanced Search** option provides a single search criteria field into which a required word or phrase can be entered. The first field provided is initially set to search only the **Title** field with a wildcard **Contains** search profile (i.e. the word or phrase can exist anywhere within the title field). Clicking the **[Search]** button beneath the search criteria text field will start the search on the database, and display matching records. === Changing the Search Field === The targeted field for a search criteria can be changed by clicking the first drop-down menu on the row. The data fields targeted can be: * Contributor (including authors, illustrators, editors etc.) * Publisher * Series * Category (may only be available on some license levels) * Keyword * Language (may only be available on some license levels) * Subject * Location * Audience === Changing the Comparison Type === The type of comparison that will be made against the targeted field can be changed by clicking the second drop-down menu in the row. The types of comparison that can be made are: * **Contains** (the word or phrase can be at any point within the targeted field, and affixed by further text or none) * **Equals** (the entire word of phrase must match the contents of the targeted field exactly) * **Does not equal** (the entire word of phrase must **not** match the contents of the targeted field exactly) * **Begins with** (the targeted field starts with the word or phrase, but then can continue with further text or none) * **Ends with** (the targeted field ends with the word or phrase, but can start with additional text or none) * **Less than** (the targeted field is textually less than the word or phase: a < b) * **Greater than** (the targeted field is textually greater than the word or phrase: b > a) * **Less than or equal to** (the targeted field is textually less than or equal to the word or phrase) * **Greater than or equal to** (the targeted field is textually greater than or equal to the word or phrase) ---- ==== Adding Further Search Criteria ==== Additional search criteria can be added and removed from the list of criteria by clicking the **[+]** and **[-]** symbols at the end of a row. If there is only a single row in the criteria list, only the **[+]** symbol will appear so that you can never remove the last remaining criteria row. All rows after the first are given an additional prefixing drop-down menu containing the boolean options **[AND]** and **[OR]** which can be used to determine how each additional criteria row is integrated into the overall search. {{ :pergamonmystic:linkedhelp:mystichelp_opac_0012.jpg?direct&600 |}} For example: * Row1 **AND** Row2 - the criteria in row 1 **AND** the criteria in row 2 must both be true for a specific record to be returned and displayed on the screen. * Row1 **OR** Row2 - the criteria in row 1 **OR** the criteria in row 2 can either be true for a specific record to be returned and displayed on the screen. ---- Next: [[PergamonMystic:linkedhelp:listsandprojects|OPAC - Lists and Projects >>]] ---- {{:logo.png?nolink |}}\\ [[:pergamonmystic:linkedhelp|Mystic Linked Help Files]]\\ [[:start|Pergamon Wiki Home]]
