Interesting project osmand user here mainly in Germany.
In some cities osm data is far more accurate when t comes to opening hours or if a shop actually still exists compared to Google maps. However searching for them is a pain that one needs a bug improvement.
Since I can't rely on the search I usually try to find the poi category and click though the results,super markets,restaurants, pharmacy,atm etc works but so many cliks and caveats. Search needs massive improvement.
Every few years I stumble across the same java or mongodb issue.
I google for it, find it on stackoverflow, and figure that it was me who wrote that very answer. Always have a good laugh when it happens.
Usually my memory regarding such things is quite well, but this one I keep forgetting, so much so that I don't remember what the issue is actually about xD
annoyed by that too, weirdly enough they pop up for certain queries and for others they don't. i have also seen that for github issues ..
but i switched to https://www.ecosia.org/ as my main search engine, and i like the results much more than on google - nothing special, but somehow more reliable/predictable. and meanwhile you plant some trees :P
