{{:pergamonmu:opac:opac-advanced-search.png?direct&200 |}}The [**Advanced Search**] menu option allows reader to access a more comprehensive search system - useful if they have specific ideas of what they need in the catalogue rather than general words or phrases.

The Advanced Search system starts with a single row of drop-down controls allowing the reader to select the database catalogue field that they with to search and the type of comparison to be made, followed by a text field to enter the criteria.

At this time, reader can search (though some of these are not available within the Pergamon Mu release of software):

  * Title
  * Contributor (e.g. Author)
  * Publisher
  * Series
  * Category
  * Keyword
  * Language
  * Subject
  * Location
  * Audience

Readers are permitted to compare these fields using:

  * **__contains__** - the criteria is anywhere in the field selected.
  * **__equals__** - the criteria is an exact match.
  * **__does not equal__** - the field is NOT the criteria entered.
  * **__begins with__** - the field starts with the criteria entered.
  * **__ends with__** - the field ends with the criteria entered.

Three command buttons are available beneath the criteria:

  * **__Search__** - Starts the search using the criteria entered.
  * **__[+]__** - Adds another row so that more criteria can be entered, including a drop-down to select whether the combination should be used in a logical **AND** or **OR** manner.
  * **__[-]__** - Removed the last criteria row from the list.

Any results from the search are displayed below the criteria box.
