Including any of the words AND
, OR
, or NOT
in any of your searches will enable
boolean search. Those words must be UPPERCASE. You can use this in all searches, including using
the search parameter, and using search filters.
This allows you to craft complex queries using those boolean operators along with parentheses and quotation marks.
Surrounding a phrase with quotation marks will search for an exact match of that phrase, after stemming and
stop-word removal (be sure to use double quotation marks — "
). Using parentheses will specify order of
operations for the boolean operators. Words that are not separated by one of the boolean operators will be
interpreted as AND
.
Behind the scenes, the boolean search is using Elasticsearch's query string query on the searchable fields (such as
title, abstract, and fulltext for works; see each individual entity page for specifics about that entity). Wildcard
and fuzzy searches using *
, ?
or ~
are not allowed; these characters will be
removed from any searches. These searches, even when using quotation marks, will go through the same cleaning as
described above, including stemming and removal of stop words.
Search for works that mention "elmo"
and "sesame street"

"cookie"
