How do I search for an exact phrase, with more than one word, e.g. "East London Line"
This from the FAQs is not very helpful - or at least I can't understand it:
Search for keywords:
Place + in front of a word which must be found and - in front of a word which must not be found. Put a list of words separated by | into brackets if only one of the words must be found. Use * as a wildcard for partial matches.
