Each term may be preceded by the standard Boolean operators
not, and, or or. If you search for
"articles not poems", you'll find all documents
containing the word "articles" except those
documents which also contain the word "poems". If
you type in "and nri and article and poems", you'll find
only those documents which contain all three search
terms. The default value is or. Thus, a search for
"nri article poems" would return pages with at least
one of the three terms.
Shorthand notation works too. A search on "articles
-nri" is equivalent to the first example, and "+nri
+article +poems" will return the same documents as the second.
If a search term has at least one capital letter, like "parIS",
the search will be case sensitive with respect to that word - that is,
only documents containing "parIS" will be found. On the other
hand, lowercase words like "paris" will generate hits
from "Paris", "PARIS", or "parIS".
To group a collection of words, use quotes. For example, the query
"Zoltan Milosevic" (quotes included) would not generate a hit
from "Slobodan Milosevic met with Zoltan Smith". Without quotes,
the sentence would count. Boolean operators can also
act on quotations: a search on '+the +kitten not "the
kitten"' would return only those documents where
"the" and "kitten" appear separately.
NRIOL SiteSearch finds words, not strings. A search for
"in" would turn up only that word, not "bin",
"inside", or "acquaintance". To perform a
string search, preface your term with the dollar sign - a
query on "$in" would find all words lists above. Note
that more complex wildcard searches using the asterisk are
not permitted. Including the asterisk in your query will
return a list of all files, but that's its only function.
