I am surprised that the search feature on geocaching.com seems to lack some features. The main thing I want to be able to do is to search for specific text in the cache descriptions. For example, my wife and I much prefer hunting for caches in parks. There are many caches in the Cleveland Metroparks system, but a search for "Cleveland Metroparks" in the keyword field only pulls up about 7 caches that happen to have those words in the title. People who place caches in the parks often include phrases like "This cache has been placed with the kind permission of Cleveland Metroparks". I would like a way to find all caches that have "Cleveland Metroparks" included in their description.
I would also like a way to search by title rather than just keywords. Sometimes I remember the title of a cache I want to revisit, and using the keywords field gives me more than I want.
Is there some feature of the geocaching.com site I'm missing? If not, is there an official way to get this suggestion to those who might act on it?
