When searching, it's not possible to save the classification field, which determines whether looking for original works, fan works, or both. This is because the query parameter sent is "classification" (all code from SearchIndex.jsx):

const data = {

page: newPage ? 1 : page,

payment: payment,

classification: classification,

order_by: order,

search: search

}

...

getRequest('/api/v3/omnisearch/projects', data, (err, jsonData) => {

...

But data is populated with the parameter "cl" (line 251):

const [classification, setClassification] = useState(urlParams.get('cl') || 'all')

If that were changed to look for urlParams.get('classification'), it'd work without issue.
