Making use of Saved Searches in Evernote
These are the ones I find most useful:
All notes tagged by a particular tag = tag:[tag name] e.g. tag:cooking
Apart from that there are two search functions that work with the "created" and "updated" time stamp fields on a note.
The created time stamp searches:
Any note created today = created:day
Any note created yesterday = created:day-1 – created:day (that is a concatenation of search terms)
The search term created:day -1 (matches any note created yesterday or today)
Any note created this week = created:week
The updated time stamp searches:
Similarly those time values can be used in searches against the updated time stamp field
Any note updated today = updated:day
Any note updated yesterday = updated:day-1 – updated:day (again using a concatenation of search terms)
Any note updated this week = updated:week
To save a search use File>New Saved Search and give the search a name.
Any that you save will appear under the saved searches collection:
