We have the option to enter tags for each fuel-up or note. We used to be able to enter a tag into the "search" field of our log book, and it would only display those fuel-ups with that particular tag.
It looks like the search function only searches the text in the note field right now, and won't search the tags. I'm not sure how long this has been broken, as I tag a lot of fuel-ups, but I don't use them to search very often. For example, I have dozens of entries tagged with "maintenance" but when I search for that term, only one post comes up which has "maintenance" in the note text.
I asked Freddie to take a look into the old source code since the Search example doesn't describe/indicate tag searching.
This is what he found:
I checked the old code that did the search from the fueluplog and it did not do tag searching.
The only way to tag search is to find a fuelup in the view all fuelups page, with the tag, then click on it. That will then just display those fuelups with that tag.
This is the same behavior as Old Fuelly.
Of course, we'll consider adding tag searching to that field in the future.
