Steps to Reproduce

1. Create a custom field of short text type
2. Populate some issues with random values
3. Use JQL Advanced Search using the custom field

Expected Results

Whenever you search, it should return all the matching cases

Some cases, randomly, are not returned by the search

Workaround
