- SEARCHING or SORTING is a very simple process of looking through all of
- the records in a database for those records that match a specified
- condition (for instance you may sort the Food database for all those
- canned foods that are single servings).
-
- In order to begin a sort you must select the SEARCH menu option from the
- top menu and select the DEFINE COMMON CHARACTERISTICS submenu item. You
- will be presented with a blank Information Card with numbers in each of
- the data fields. To search a particular data field simply enter (at the
- flashing prompt found at the bottom of the screen) the number of the
- field.
-
- FOR INSTANCE:
-
- To search the Food file to find all the types of SOUP you have in your
- inventory simply enter the number 6 at the prompt. Next you will be
- asked to enter the operator for the search. You will notice a list of
- numbers identifying the type of operators you may select. In our example
- we are searching the Food File for SOUP so we would select the first
- operator (1 - is equal to).
-
- Finally you are asked to enter the data to search FOR - in this case
- 'SOUP'. It is important that you enter the search data perfectly
- because the program will search for all records that contain what you have
- LITERALLY typed. You would next be presented with the main screen showing
- only those records that match your search criteria.
-
- You may save this SubFile to the hard disk or you may simply print the
- list and then re-load the Main File. It is possible to have as many
- SubFiles as you have storage capacity and furthermore you may even do
- searches on SubFiles. In fact there is really no limit as to how deeply
- you nest the sorts (you could do a sort on a sort on a sort on a sort
- ....). By nesting the sorts you can search for very complicated criteria
- (e.g. all Maintenance Items that fall under the category Engine and are
- scheduled prior to August 1st and have not been done since May 1st!)).

- SUMMARY
-
- Searching is THE most important aspect of the Shelter Island Press system.
- It allows you to find and manipulate data very quickly. By nesting the
- searches (sorting on a sort of a sort....!) you can utilize the full power
- of the database.
