    4747== Advanced Queries ==
     48It is possible to query changesets on the OSM server based on four criteria:
     49  * based on the changeset owner
     50  * based on whether the changeset is open or closed
     51  * based on when the changeset was created or closed
     52  * based on the area which is affected by the changesets
     53
     54The '''Advanced''' tab provides a UI for defining a changeset query based on these four criteria. There are four checkbox you can select, one checkbox for each kind of query restriction, see below. If a checkbox is selected the respective query restriction will be applied in the query. Depending on the checkbox you select, additional parameters have to be entered, please refer to the following sections.

     62You can either restrict the changeset to
     63 * changesets owned by yourself. Note that this option is disabled if you are running JOSM in anonymous mode, i.e. if you don't have an OSM user account or if you didn't enter its name and its password in the JOSM preferences.
     64 * a specific user given its user ID. This is the most precise query option for user based query because the user ID is guaranteed to be unique.
     65 * a specific user given by its user name. This is a slightly less precise query because, for historical reasons, the same user name could be assigned to more than one user.

     73The OSM API currently supports two kinds of date/time based queries.
     74 1. In the first query you have to supply a date/time as parameter. The OSM server replies all changesets ''closed after'' this date/time.
     75 2. In the first query you have to supply ''two'' date/time values as parameters. The OSM server replies all changesets ''closed after'' the first date/time and ''created before'' the second date/time.
     76It is not intuitively clear why the OSM server provides exactly these two features for date/time based changeset queries but as of API 0.6 (the current API version) that's what JOSM can and does support.
     77
     78Date/time values have to be entered as two seperate values: (1) a date value and (2) a time value. The time value is optional. Both date and time values can be entered in the format familiar in your locale. Hover over one of the date or time fields to see the list of supporte formats in the tooltip text.

     84Changesets can be queried based on the area they cover. In order to restrict a changeset query to a specific area you have to enter its bounding box.
     85
     86Either enter the lower left (minimum latitude/minimum longitude) and the upper right (maximum latitude/maximum longitude) corners or copy/paste a download URL for a specific area in the field URL.
