{% trans %}See also: About Scholarly Search{% endtrans %}
{% trans %}This service provides fulltext searching over research publications archived in Internet Archive's various collections. It includes content from the natural sciences, humanities, biomedicine, art, history, industrial research, government reports, and more.{% endtrans %}
{% trans %}Reader access to the content is provided when possible. Sometimes this access is to a "pre-print" or other version of the work, and this is indicated in the search results.{% endtrans %} {% trans %}In other cases, depending on search filters, results are included for which there is only a bibliographic catalog entry. It may still be possible to obtain access through a public library or from the publisher directly.{% endtrans %}
{% trans %}In addition to the basic filtering and sorting options, this search
interface also allows the use of Lucene query syntax in the search box. You can
restrict term queries on multiple metadata fields using colon statements like
journal:Science, set filters like lang:de, and
apply range queries like year:>1989 year:<2000.{% endtrans %}
{% trans %}While this syntax allows for relatively complex and powerful queries, at some point advanced users may run into limits on the size or complexity of queries.{% endtrans %} {% trans %}For the time being we recommend systems like lens.org for a more powerful interface.{% endtrans %}
{% trans %}Search for digitized pages about a topic from specific years:{% endtrans %} {{ example_search_box('"egyptian pyramid" access_type:ia_sim year:<2000') }}
{% trans %}Search for papers in Chinese matching a term:{% endtrans %} {{ example_search_box('lang:zh 临床表现多样') }}
{% trans %}Conference papers with an author name query:{% endtrans %} {{ example_search_box('type:paper-conference author:"natasha noy"') }}
{% trans %}As an experimental feature, if the search query "looks like" a formal citation, as found in the bibliography of a research paper, the service will attempt to parse the citation and do a match against our catalog of known works. When this happens, any filters are ignored.{% endtrans %} {{ example_search_box('Spertus, Ellen. "ParaSite: Mining structural information on the Web." Computer Networks and ISDN Systems 29.8-13 (1997): 1205-1215.') }}
{% trans %}You can restrict to records where the field exists with an asterisk like doi:*, and negate any term like !type:article-journal.{% endtrans %}
{% trans %}In-depth documentation of the query syntax is available from the Elasticsearch project.{% endtrans %}
{% trans %}The complete current search document schema is available (as JSON) in the source code.{% endtrans %}
