To refine your search you can combine your search strings with AND, OR, NOT and NEAR and phrases can be quoted:
water OR waste searches for either of these words
oceans AND biodiversity searches for blocks with both words
pollution NEAR water searches for blocks with either of these words, with them being closer ranks higher
"climate change" searches for this phrase
