A filter is a statement that a user constructs using a field, a value to compare the field to, and an operator to make the comparison between the field and the value. Users may combine several filters to refine search results.
For Example: A user may create a simple find that lists all patrons who are male. Alternatively, a user may create a find that lists all patrons who are male, 19 years old, and live in a particular residence hall.
When using more than one filter in a find expression, users can group the statements using either an At Least One is true or an All are true condition. To switch between the conditions, select the condition and click on the All / At Least One link.
Use the Put in Group button to add a filter to another group within the expression. Clicking Ungroup will move a filter from a sub-group up into the parent group above it in the expression hierarchy.
To move a filter, select it and click the Move button. Then select another filter (or filter group) and click Move Here to move the filter to that location.
To remove a condition, select it and click on the Remove button.
