I really like the UI changes made. However, I am finding a bug that's been hard to reproduce. Sometimes, the screenshots aren't sized appropriately. Have you experienced this?

Also, some of the search results seem too far removed from the search query. The term "create and edit geometries" for example. It might be worthwhile altering our scoring system.

I haven't been able to replicate the screenshot size issue you're seeing.

What is wrong with the search results for "create and edit geometries"?

We return results based on key words found in the sample title, category, description and tags. Results that are far removed from the query will contain a subset of the searched keywords.

we can later optimize search results if we choose
