If you open the stats screen and click on some things like the bars or the heatmap squares, the browser pops up with a search. These searches are… less than ideal.
For example, clicking on “Learning” in the pie chart searches for this:
deck:current (-"is:review" AND "is:learn")AND -("is:buried" OR "is:suspended")
Notice the space at the start, the unnecessary "AND"s, the quotes, etc. A new user might look at this and think that Anki searches are impossible to learn.
A better way to write the above search is:
deck:current is:learn -is:review -is:buried -is:suspended
