Search objects in the current data layer
You need to choose one of the search and select modes:
- replace selection
- add to selection
- remove from selection
- find in selection
If you check add toolbar button, as soon as you click on Start Search, a button will be added to the Main Toolbar which will execute the defined search expression each time, you press the button. You can also set an own icon for this button in the Toolbar Preferences. As with any "button" you can always assign shortcut to it.
Some examples of queries:
- type:way selects all ways
- name:Herrengasse selects all elements with the given name
- name=Herrengasse same as above, but case sensitive
- "name"="Herrengasse" same as above, but works also with special characters like white spaces in the value
- type:way name:- selects all ways that do not have a name
- id:123465678 selects an object (way or node) with a particular id
- timestamp:2010-11-01/2010-12-01 selects object with last change in November 2010
There is also a very under-used and under-documented feature that lets you enter a web URL (file://, http://, https://, ftp://) in the search field. JOSM will then attempt to load that URL, and select any objects that it finds referenced in that file. JOSM will look for XML tags "way", "node", and "relation" in the document, and use their id attribute. This means you can access another OSM file on your hard disk this way and have JOSM select all objects that are present in the file (provided they are present in JOSM's dataset too).
The special expressions selected and modified select all currently selected resp. all objects modified in the current session.
