query copied into search box results in an error

Overview: Copying a query into the search box and clicking "Search" results in an error. NB: copying a single value, e.g. rapport works fine; this is specifically about copying a whole query
Steps to Reproduce:

1. Log into snapshot as a user with permission to conduct searches in ui-inventory
2. Begin typing the following query, allowing auto-complete to finish it:

   "Title (all)" = rapport 
   

3. Click "Submit" and get results. Yay!
4. Copy the completed query
5. Click the "Reset all" button
6. Paste the completed query
7. Click the "Submit" button

Expected Results: Results. Yay!
Actual Results: JS alert with the following text, pulled from the 400 response from mod-search:

{"errors":[{
  "message":"Failed to parse cql query [cql: '(keyword all \"\"Title (all)\" = rapport \") sortby title', resource: instance]",
  "type":"SearchServiceException",
  "code":"service_error"}],
  "total_records":1
}

Note: copying an entire URL works (sort of; see UIIN-1637) so it is possible to bookmark a search or share a link with a colleague; it is merely copying a query directly into the search box that does not function.
