<h1>{% trans %}Scholar User Guide{% endtrans %}</h1>
<p><i>{% trans %}See also: <a href="{{ lang_prefix }}/about">About Scholarly Search</a>{% endtrans %}</i>

<p>{% trans %}This service provides <a href="https://en.wikipedia.org/wiki/Full-text_search">fulltext searching</a> over all 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 %}
<p>{% 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 %}

<h2>{% trans %}Query Syntax{% endtrans %}</h2>

<p>{% 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
<code>journal:Science</code>, set filters like <code>lang:de</code>, and
apply range queries like <code>year:&gt;1989 year:&lt;2000</code>.{% endtrans %}

<p>{% trans %}While this syntax allows for relatively complex and powerful queries, at some point advanded users may run in to limits on the size or complexity of queries.{% endtrans %}
{% trans %}For the time being we recommend systems like <a href="https://lens.org">lens.org</a> for a more powerful interface.{% endtrans %}


<h3>{% trans %}Example Queries{% endtrans %}</h3>

<p>{% trans %}Search for digitized pages about a topic from specific years:{% endtrans %}

{{ example_search_box('"egyptian pyramid" access_type:ia_sim year:<2000') }}

<p>{% trans %}Search for papers in Chinese matching a term:{% endtrans %}

{{ example_search_box('lang:zh 临床表现多样') }}

<p>{% trans %}Conference papers with an author name query:{% endtrans %}

{{ example_search_box('type:paper-conference author:"natasha noy"') }}

<h3>{% trans %}Citation Queries{% endtrans %}</h3>
<p>{% 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.') }}

<h3>{% trans %}Metadata Fields{% endtrans %}</h3>

<p>{% trans %}You can restrict to records where the field exists with an asterisk like <code>doi:*</code>, and negate any term like <code>!type:article-journal</code>.{% endtrans %}

<p>{% trans %}In-depth documentation of the query syntax is available <a href="https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-query-string-query.html#query-string-query-notes">from the Elasticsearch project</a>.{% endtrans %}

<p>{% trans %}The complete current search document schema is available (as JSON) <a href="https://github.com/internetarchive/fatcat-scholar/blob/master/schema/scholar_fulltext.v01.json">in the source code</a>.{% endtrans %}

<h2>{% trans %}Work In Progress{% endtrans %}</h2>

<div class="ui yellow message" style="color: black;">
  {% trans %}This service is in "alpha". It has several bugs, experiences downtime, and has not been officially announced.{% endtrans %}
</div>

<p>{% trans %}This project is currently a <i>prototype</i>{% endtrans %}

<p>Some known bugs and issues:

<ul>
  <li>web.archive.org PDF links sometimes return "not found" errors. This is impacting up to 1% of recent papers. In almost all cases there is a preserved copy of the file that should be available.
  <li>Poor metadata quality for conference proceedings. Many are labeled "unpublished" and are not associated with the conference.
  <li>Duplicate versions of same work. Eg, different versions of the same paper or dataset. We are working on basic entity-deduplication in the fatcat catalog.
  <li>Mis-matching of file content or version with work metadata. For example, sometimes pre-prints or author manuscripts are incorrectly associated with version-of-record metadata, or vica-versa.
</ul>
