     Import special phrases.

+
+    Special phrases are search terms that narrow down the type of object
+    that should be searched. For example, you might want to search for
+    'Hotels in Barcelona'. The OSM wiki has a selection of special phrases
+    in many languages, which can be imported with this command.
+
+    You can also provide your own phrases in a CSV file. The file needs to have
+    the following five columns:
+     * phrase - the term expected for searching
+     * class - the OSM tag key of the object type
+     * type - the OSM tag value of the object type
+     * operator - the kind of search to be done (one of: in, near, name, -)
+     * plural - whether the term is a plural or not (Y/N)
+
+    An example file can be found in the Nominatim sources at
+    'test/testdb/full_en_phrases_test.csv'.
+
+    The import can be further configured to ignore specific key/value pairs.
+    This is particularly useful when importing phrases from the wiki. The
+    default configuration excludes some very common tags like building=yes.
+    The configuration can be customized by putting a file `phrase-settings.json`
+    with custom rules into the project directory or by using the `--config`
+    option to point to another configuration file.
