@organisation for organisation search

!word to exclude word
"word" or 'word' for title search

csw query syntax tested on default profile

 #word : search in keywords
 @word : search for organizations
 "word" or 'word' : search in title|alternatetitle
 +word : exact word match
 -word : to suppress entries with a specific word
 word : full search
new parameter CSW_FILTER_PROPERTIES to restrict full text search to some queryable properties

?word performs an AnyText search
wilcards allowed for the user
=> falls back to strict search
