Using Opensearch as a developer
Introduction
Evergreen responds to OpenSearch requests. This can be a good way to get search results delivered in a format that you prefer.
Throughout this section, replace <hostname> with the domain or subdomain
of your Evergreen installation to try these examples on your own system.
Opensearch queries will be in the format
http://<hostname>/opac/extras/opensearch/1.1/-/html-full?searchTerms=item_type(r)&searchClass=keyword&count=25
In this example,
- 
html-full is the format you would like. html-full is a good view for troubleshooting your query. 
- 
searchTerms is a url-encoded search query. You can use limiters in the limiter(value)format. For example, you can use a query likeitem_lang(spa)
- 
count is the number of results per page. The default is 10, and the maximum is 25. 
Other options include:
- 
searchSort and searchSortDir, which can be used to display the results in a different order (e.g. for an RSS feed).
