| query_parser is a components used by both history and bookmarks to avoid having | |
| a cyclic dependencies between the two components. It only exports types used to | |
| parse and normalize queries into the history search. | |
| query_parser is not allowed to depend on content/, because it is used by iOS. | |
| If dependences on content/ need to be added to query_parser, it will have to be | |
| made into a layered component. See [1] for more information. | |
