The best way to keep your data clean & useful is to regularly do some easy tending and pruning.

WHY WOULD I LOOK AT OLDER NOTES?

Face it, when you started using Evernote you weren’t sure what to put in. Or you followed the idea of "dump everything in it" to the letter and now every search has way too many irrelevant results. Or you realize that your "how to use Evernote as a cookbook" period is over and you no longer need those entries.

Or you wish you would have tagged some notes. Or you would like to move personal notes to one notebook and article clippings to another.

An easy way to tend to this data household chore is by doing a search for notes created on that day in the years before.

Example: if today is December 28 then I can find the notes I made on December 28, 2009 by typing:

created:20091228 -created:20091229

The format there is since date, before date, and the result is a list of notes created on the since date only.

To view other years I simply change the year. My data goes back to 2005 when I started to use Evernote so it takes 5 searches.

I’m done with my data pruning in 1-2 minutes usually.

HOW I USE DATA PRUNING

• I delete a lot of material that is outdated or no longer piques my interest.
• See times gone by as I come across log entries.
  
• Add or remove tags
• Move items to new notebooks
• Consolidate notes, tags or notebooks
• Tweet older but interesting material
• See the big(ger) picture in areas of interest
• Get ideas for blog posts, articles

BONUS TIP: PERSONALBRAIN

I use the same pruning procedure in PersonalBrain. The reports tab lets you pick a start/end date.It’s a bit more clicking with the calendar it has but it’s pretty cool to have your data in order.
