Date filtering is a very common need and would be a useful enhancement (user opinion, not a maintainer).
I use options 1 and 2, sometimes together. Option 1 only works if you have timestamp, creationdate, and modificationdate showing in the entry table. You can enable these columns in preferences, if you have not already.
Regarding option 2, it’s true that filtering by day and month can get pretty complicated. However, filtering by year is easier and often useful without being precise.
In case you are unfamiliar,
\dmeans any digit.\d+means one or more digits.[0-9]means any digit from0through9[012379]means 0, 1, 2, 3, 7, or 9
Here is a basic pattern for all the years in each decade.
199[0-9]
200[0-9]
201[0-9]
202[0-9]
Adjust the range to search within a decade.
- 2021 through 2024:
timestamp=~202[1-4]
Combine with | (“or”) to make a multi-decade range.
- 2015 through 2025:
timestamp=~201[5-9]|202[0-5] - 2005 through 2025:
timestamp=~200[5-9]|201[0-9]|202[0-5]
Note: These examples are designed for easy composition, not necessarily for performance (processing efficiency). That is, you can easily adjust the range of each decade without rearranging anything else, unlike in this example, which gives the same results as the last one above: timestamp=~20\(\([01][5-9]\)|\([12][0-4]\)|\(25\)\)
Searching with =~ enables regex searches of the specified field. In this case, the regex button does not need to be activated (See Searching within years - #5 by horror-vacui)
