A filter enables you to refine your search criteria further, by adding some additional search criteria. A filter can be applied before running a search or it can be used to refine search results after the initial search has been executed. For example, you might want to find all reservations activated on a particular date as opposed to all reservations. A number of default filter options are provided for different searches.
Click one of the filter options to display entry boxes for you to enter your criteria, e.g. Series.
Use the scroll bar on the right for long lists.
Select e.g. Begins with; enter the basic search criteria or a wildcard % in the search refinement box.
You can select more than one Filter criteria to further refine the search. OLIB displays all filters under the search box.
This is at the top of the Refine Search dialog above. Use this to type part of a field name, e.g. "op" to navigate directly to that field to filter on it.
For example:
The Search Fields box is only shown if there are more than 15 fields listed in either column.
(The search provides firstly the items whose value starts with the letters entered, then items containing words that start with the letters entered, and finally items containing the letters entered anywhere in their value. listed in either column).
The Linked Domains are in an initially collapsed list accessible by clicking on Linked Domains.
If you enter text in Search Fields that is not found on the main fields, OLIB automatically searches for it in Linked Domains and shows matching fields below.
See also the various Filter Operators that are available; on List, on Value, on Date.
The search is re-executed with the new filter details.
If a filtered search would be useful to keep for future use then you can keep it as a Saved Search. All the filter details are saved in the search together with the filter search criteria. The filter remains in place until you close the search window or click Delete on the filter. Note that all filter values are case sensitive. Filters can be permanently disabled or their names can be changed by the system manager: Change filter names.
The system administrator can control what fields are available for filtering in the Refine Search dialog (including the Linked Domains). This is now manageable through the Enable Filter flag on the attribute record:
Note that for the changes to take effect you need to rebuild OLIB Web. Filters can only be applied to attributes which have a value for "Constrain" as this defines how the filter should be applied (e.g. Text, Date or Number).
