class ImportSpecialPhrases:
"""\
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.
