I'm a developer at Social Edge Consulting and I'm going to build new widget, the advanced search widget. For that I want to use REST API with calls being sent from frontend JS. I need to set many different filters for the search, for example I need to know how (if?) I can get only the answered questions in search results.
Even if platform rules suggest to use Widget API instead, search API there also doesn't seem to have any "Filter" field description.
I'd recommend starting with documentation here: https://community.telligent.com/community/8/w/api-documentation/45183/search It's filed under an older version, but our usage of SOLR search syntax hasn't changed since then.
You can also check our own Search Results List widget used on the Advanced Search page. Go to Administration > Interface > Widgets and search for Search Results List.
We also have some general documentation here: community.telligent.com/.../list-search-result-rest-endpoint
Ummm... nevermind, I found the answer. I didn't find this in the documentation though, I discovered this from the search results.
You can use these filters...
