* New possibility to invoke user queries from a search expression From the search field: `S:"My query"`. Can be combined with other filters such as `S:"My query" date:P3d` as long as the user queries do not contain `OR`. A use-case is to have an RSS filter with a stable address or an external API call with the ability to update the user query. * Draft of parenthesis logic * More draft * Working parenthesis (a OR b) (c OR d) * Working (A) OR (B) * Support nested parentheses + unit tests + documentation * search:MySearch and S:3
