The whole site has been text-indexed i.e. the text of all pages is searchable but not hypertext links. For users, a search is similar to using Google; a preceeding minus character excludes a word, while phrases are supported within double-quotes. The logical OR and NOT operators are also supported.
The returned pages are ranked according to how often the search words occur and where.
NOTE: I am English and I use English words i.e. Colour not Color, Jewellery not Jewelry, Lift not Elevator, Pavement not Sidewalk etc etc.
Czech language uses the letter "z" quite often. Bear this in mind if you are searching for information on Pensions (Penzions) or Museums (Muzeums).
