The following error message appears when attempting to use slop with a match_phrase query: Error: {'status': 400, 'error': {'type': ['invalid_request_error'], 'message': 'Query clause [query] not allowed or invalid field name.'}} Adding slop functionality would allow users to more effectively prospect for leads or search for candidates. For example: { "match_phrase": { "job_title.text": { "query": "director sales", "slop": 1 } } } This would return "director of sales" and other relevant titles without having to either use the Autocomplete API or the Job Title Enrichment API.
