| * Create a single term query from the input value equivalent to readableToIndexed(). |

| * <p> |
| * For text fields, no analysis is done since raw terms are already returned from the faceting |
| * and terms components, and not all text analysis is idempotent. |
| * To apply analysis to text fields as well, see the {@link FieldQParserPlugin}. |
