PROPOSED OPERATORS
------------------  
    Prefix, ie starts with:
        possibilities: * or ^ or ...
        { key => { '*' => value }}
        { key => { '^' => value }}
        { key => { '...' => value }}

    Wildcard, ie shell wildcards ? *
        possibilities: ** or *?
        { key => { '**' => 'f?o*'}}
        { key => { '*?' => 'f?o*'}}                

    Fuzzy, ie Levensthein distance:
        proposed:  *~
        { key => { '*~' => 'f?o*'}}

    Text, ie full text search, eg "foo bar"
        proposed: ~
        { key => { '~' => value }}
    
    Query string, ie full text search with special query syntax
    eg 'foo AND bar AND "this phrase" town:(london OR paris)'    
        proposed: ~~
        { key => { '~~' => value }}
