search: integer and float don’t support exact match

[TanyaStere42]

Expected Behavior

Users can get exact matches back for integers and floats in either individual or sighting search

Current Behavior

1. open individual search
2. set sighting count filter to “equals”
3. enter 1
4. click go
5. wait. no results are returned

there is an error

"root_cause": [
      {
        "col": 97, 
        "line": 1, 
        "reason": "[range] query does not support [eq]", 
        "type": "parsing_exception"
      }
    ],

QA Verification

Default fields (the individual search sighting count is the only default search we have for this issue)

• Individual search, set sighting count filter to "equals"
• enter an integer (i.e., 1)
• click go
• results returned

Custom fields

• Create a custom number field for a sighting
• Sighting search, set custom field filter to "equals"
• enter an integer (i.e., 1)
• click go
• results returned
