Please check out the latest version of ECHOcommunity Search. When a term is searched, you will first see the Basic Search which provides a limited list of filters - Languages and Resource Type. Key Resources is an option which reduces the search list to only those resources which have been identified as key to ECHO’s mission. We will be identifying more resources as ‘key’ over time.
At the bottom of the left-hand list is Advanced Search. When you select that, your options expand to include Publication, Tags, Regions, et al. Key Resources is again an option, but you can also select for ECHO-only . An additional option of value is the ability to search a term within a particular publication set. For example, you can look for all of the occurrences of ‘biochar’ within Tech Notes.
Please let me know if you have any questions or suggestions.
