Issue Summary

JQL enhanced search endpoint should function in the same way as the search through the UI.
Currently exact phrase match is not working with the rest api, returning a empty array when there are issues being returned through the UI. This happens when exact search is used on custom field.

Steps to Reproduce

1. Have a text field in your project and have a ticket with a specific value (example: XXX)
2. Make an API call to /rest/api/2/search/jql for that exact value
   (example: { "expand": "renderedFields,editmeta", "fields": [ "issuekey" ], "jql": "\"custom text[short text]\" ~ \"\\\"XXX\\\"\"" }
   )

Expected Results

The response should return an array including the ticket

Actual Results

Workaround

Don't use the exact match \" for now
