 ====== Mystic Help ======
-==== Advanced Search ====
+===== Advanced Search =====
-This help file has not yet being released.
+The **[Advanced Search]** option allows readers to perform specific searches on the database in a more targeted fashion than the general search feature.
-The Mystic Help Files are being re-written for the release of **Mystic v1.5, during the summer of 2021**.
+{{ :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.
