About storage and indexing options
FileMaker Pro provides options for indexing fields and for storing the results of calculations. You can:
1 Create an index, which is a list of the values stored in a field. An index greatly speeds searches, but takes up space on
your disk. You can index text, number, date, time, and timestamp fields. You can also index calculation fields if the
results are text, numbers, dates, times, or timestamps.
1 Store the result of a calculation field in your database, or you can tell FileMaker Pro to perform the
calculation only when needed (unstored). Storing the result is faster but takes up more space on the disk.
You can specify storage options for text, number, date, time, timestamp, and calculation fields.
1 Set any field (except summary fields) to share one value across all records in a file if you select Use global
storage in the Storage tab of the Options for Field dialog box. Fields defined with global storage are also
referred to as global fields.
