LuckieIrie,
Depending on how your data is formatted, you have several options. First, you will need to determine if the documents being captured in the current view have date-formatted fields which can be referenced easily in view selection formulas. For instance, if you have a date formatted field called postdate which stores the document creation date in Notes data format, and you wish to show only documents which have been created in the last month, then you can place the following formula in the view selection formula:
SELECT (postdate>@Adjust(0;-1;0;0;0;0))
If you do not have a specific date field on each document which stores the document creation date, you can substitute the formula @Created for the field postdate giving you:
SELECT (@Created>@QAdjust(0;-1;0;0;0;0))
Keep in mind that there is a trade-off to consider when building views based on date criteria. It will take longer to index and open these views. Let me know if you come across any obstacles implementing these suggestions, or if you need help in displaying documents from a specific month, day or year.
HTH,
Simon
