Search snippets for frequently used sub-queries

[joshdoe]

I'd find it useful to save frequently used sub-queries for reuse. Think of some search queries you perform often, but in combination with other queries. For example, highways could expand to highway=motorway | highway=motorway_link | highway=secondary | .... Somewhat frequently I'll want to select the current objects, and all parents and children, so mysearchsnippet could expand to child selected | parent selected | selected. We'd need to have some way to trigger these snippets, possibly by prefixing the word with a special character. We'd also need to have a way to edit these snippets, likely in their own separate dialog.
