1.1     ! root        1: Searches via library() are done using electronic mail. That is, your search
        !             2: request is sent to a remote computer which does the search and mails back the
        !             3: results.  Usually you should have results within 20 minutes or less.
        !             4: 
        !             5: There are two search stategies available through library().  Note that these
        !             6: are search languages of the slimmer system - see slimmer documentation for more
        !             7: details than given below.
        !             8: 
        !             9: The main method is to enter a search string which library handles as follows:
        !            10:     a) It is broken up into alpha-numeric components (words) and all
        !            11:        punctuation is thrown away.
        !            12:     b) The words are used from left-to-right to find items having the
        !            13:        word (note anywhere - e.g. smith will find authors, titles, etc).
        !            14:     c) The set of items retrieved by each word is ANDed with those
        !            15:        retrieved so far, with the constraint that something always remains
        !            16:        in the retrieved set.
        !            17: 
        !            18:  Some points of interest:
        !            19:     1) If you surround something with quotes, rule a above is bypassed.
        !            20:        I.e. to search on the word  CP/M   enter "cp/m" otherwise the
        !            21:        slash will cause it to search on   'CP AND M'
        !            22:     2) Authors are in the indices in the form  LAST FM, i.e.
        !            23:                WALDSTEIN RK
        !            24:        Searching on WALDSTEIN will retrieve everything by any author with
        !            25:        last name WALDSTEIN. To search a particular author use "WALDSTEIN RK".
        !            26: 
        !            27: A more complex full Boolean search capacity is also available. It is
        !            28: used if the search string begins with a parenthesis "(".
        !            29: 
        !            30: The operators are (in order of precedence):
        !            31:   /=<field list>      restrict a set to a list of fields
        !            32:   A (f) B             results in items with A and B in the same field
        !            33:   A NOT B             results in items containing term A, NOT term B
        !            34:   A AND B             results is items containing both term A and term B
        !            35:   A OR  B             results in items with term A OR term B
        !            36: 
        !            37: So a legitimate, though overly complex search, is
        !            38: 
        !            39:   ((science (f) (fantas? or fiction))/=ti and (84 or 85)/=da) not asimov
        !            40: 
        !            41: 
        !            42:
