Librarian Sandbox
Librarian, a micro search library leveraging Boolean Operators, supporting Wildcard annotation within search terms.
Boolean Operators
AND Requires all terms to be found within the search context.
Sample: "nasa" AND "mission" AND "ganymede".
OR Requires at least one term to be found within the search
context.
Sample: "nasa" OR "mission" OR "ganymede".
NOR Negative OR, Requires no terms to be found within
the search context.
Sample: "nasa" NOR "mission" NOR "ganymede".
XOR Exclusive OR, requires exactly one term to be found
within the search context.
Sample: "nasa" XOR "mission" XOR "ganymede".
NOT Flips the outcome of AND, OR, NOR, XOR operators and/or
result of the search term.
Sample: NOT "spacex",
"nasa" AND NOT ("spacex" OR "galactic").
Wildcards
An Asterisk (*) An asterisk (*) may be used to specify
any number of characters. It is typically used at the end of a root word,
when it is referred to as "truncation." This is great when you want to
search for variable endings of a root word.
Sample: cent* (matches: center, centre), *fix (matches: prefix,
suffix), b*r (matches: beer, bear).
A Question Mark (?) A question mark (?) may be used to
represent a single character, anywhere in the word. It is most useful when
there are variable spellings for a word, and you want to search for all
variants at once.
Sample: cent?? (matches: center, centre
but NOT cents), ???fix (matches:
prefix, suffix but NOT
affix), b??r (matches: beer, bear but NOT bor).
Escaping Special Characters
An Asterisk (*), A Question Mark (?)
and A Term Boundary (") may be escaped, i.e. search
literaly as \*, \?, \" respectively.
Sample: \*note (matches: *note),
home\?
(matches: home?), \"name\" (matches:
"name").

“Saying 'I notice you're a nerd' is there like saying, 'Hey, I notice that you'd rather be intelligent than be stupid, that you'd rather be thoughtful than be vapid, that you believe that there are things that matter more than the arrest record of Lindsay Lohan. Why is that?' In fact, it seems to me that most contemporary insults are pretty lame. Even 'lame' is kind of lame. Saying 'You're lame' is like saying 'You walk with a limp.' Yeah, whatever, so does 50 Cent, and he's done all right for himself.”
