Two possible approaches spring to mind:
1. Search all three categories for each keyword,
ie 'hotel germany' would turn into
SELECT * FROM mytable WHERE
(country='hotel' OR type='hotel' OR city='hotel')
AND (country='germany' OR type='germany' OR city='germany')
2. A translator table: two text fields, 'phrase' and
'search', filled with something like:
phrase | search
'germany' | 'country=\'de\''
'states' | 'country=\'us\''
'brazil' | 'country=\'br\''
'hotel' | 'type=2'
'bed' | 'type=1'
'b\&b' | 'type=3'
'london' | 'city=31854'
'paris' | 'city=22059'
... you can then use a search through the translator
table to build the select statement that actually does
Both of these have drawbacks, mainly that the tables
they nominally reference are severely non-normalized;
I suspect the proper approach should be a series of
queries for each term among a set of normalized tables,
followed by a final constructed query... but you get
Another point: single-word searches could be a problem,
stumbling over 'New York' or 'bed & breakfast'; it might
be worth amending the search to also try consecutive-word
