Table of Contents


Both Quick Search and Advanced Search are available. For most of your search queries Quick Search is the tool of your choice. Advanced Search can be used if a term or a property must be searched precisely in a specific field.

Faceted Search

Facets are helping you to filter the result list of your search. Filtering by publication year or name of a contributor makes it easy to focus on the publications you are searching for without using complicate search rules.

Tips and Tricks

Quick Search

Quick Search uses a probabilistic search engine that applies word stemming and stop word filtering and that ranks found documents according to occurrence and frequency of the matched terms. It searches in the PDF full text, in the bibliography (authors/editors, year, title, journal/series title), in the abstract and in other fields.

Search Operators

Quick Search provides the following search operators:

Operator Description Examples
AND prion AND bovine
OR prion OR bovine
NOT prion NOT bovine
XOR finds documents that contain either one or the other term, but not both together. A bit exotic. Aguzzi XOR Glatzel
NEAR matches documents containing both terms within 10 words of each other. Order of matching terms is irrelevant. With NEAR/n (n = number) the threshold distance can be set. arab NEAR gender
ADJ matches documents containing both terms within 10 words of each other. Like NEAR, but the terms must appear in the same order as in the query. With ADJ/n (n = number) the threshold distance can be set. arab ADJ gender
emerging ADJ/1 market
+ includes documents which contain the so marked term or phrase. The terms marked with + do not contribute towards the document ranking. synthesis +drug
- excludes documents which contain the so marked term or phrase (works like NOT). synthesis -drug

All operators must be written with uppercase letters. The precedence of operators can be controlled using brackets ().

Phrase Searches

Terms within double quotes are matched exactly as written (and as written in the given order).

Example: "neurodegenerative diseases"


The only allowed wildcard is *, which matches 0 or more characters. As a trailing wildcard it can be used only at the end of a term.

Example: chlamy*


To find a term or phrase in a specific field, the field name can be added in front of it using a colon as separator. Terms can be grouped within brackets.

Field name Description Example
title Title of the publication title:philosophy
title:(mice "men")
The double quotes cause that men is not filtered as stop word.
creators_name Creators creators_name:(haas, henriette)
editors_name Editors editors_name:haas
book_title Title of a book book_title:(medical imaging)
date Year of publication date:2014
publication Title of series/journal publication:(Virology Journal)
publication:"Virology Journal"
keywords Uncontrolled keywords keywords:drug

Tips and Tricks

Finding publications by ORCID iD : Just paste the ORCID iD of a person in the search bar. Example: 0000-0003-3841-6207

Also subjects and institutes can be searched. For this, the Dewey Decimal Classification code or the numbers of the institutes must be used. This information can be obtained by clicking a subject in the Dewey Decimal Classification or an institute in Communities & Collections and by extracting the relevant ddc notation or number from the URL.

Examples: ontologies ddc000 finds publications on ontologies in computer science (Dewey Decimal Classification 000).
testament 10236 date:2013 finds publications of the Institute of Theology that contain the term "testament" and were published in 2013.

Mathematical equations can be searched using LaTeX notation. Example: $\sin^2 \theta_W$ can be searched using the notation \sin^2 \theta_W.

Advanced Search

Advanced Search provides several fields from ZORA. By clicking the "?" button at the respective field, a short explanation about the field and its allowed contents can be displayed. In Advanced Search, the previous operators and rules of Quick Search do not apply. Terms are always matched exactly, except if wildcards are used.


Allowed wildcards are % (matching exactly 1 character) or * (matching 0 or any number of characters).

Matching Terms within a Field

A drop down menu in front of a field allows to choose between "all of" (all terms must match, Boolean AND) or "any of" (any of the terms can match, Boolean OR). Default is "all of".

Match Conditions for Fields

At the bottom of the form, at "Retrieved records must fulfill", a drop down menu allows to choose between "all of these conditions" (Boolean AND search) and "any of these conditions" (Boolean OR search). Default is "all of these conditions".

Index Browsing

Publications can be browsed using five different indexes:

  • Publication Year
  • Creators & Editors - Names can be looked up by entering a family name, one or several initials, and/or an ORCID iD. For the index, names are merged into distinct family names and initials(s), e.g. publications having Muster, Katharina or Muster, Karl as authors are merged into one index entry Muster, K (fuzzy search). An additional index entry is created for names that have an ORCID iD, e.g. Muster, K 0000-0001-2345-6789, and all name variants for this ORCID iD are listed, e.g. Muster, Katharina Esther, Muster Katharina E, Muster Katharina. A precise publication list can be obtained from this index entry. Therefore, tagging your publications with your ORCID iD is recommended.
  • Communities & Collections - Faculties, institutes, selected journals and special collections.
  • Dewey Decimal Classification (DDC) - Publications are classified automatically based on their communities assignment and in addition manually by the submitters. General subjects (first 3 digits) are used only. About 90% of the publications have a DDC assignment.
  • Scopus Subject Areas - Publications are classified automatically with fine-grained Scopus Subject Areas if they have an equivalent record in Scopus. About 50% of the publications have a Scopus Subject Area classification.

Display of Results

After searching using Quick Search, results are initially ordered by relevance (occurence, weight, frequency and position of matching query terms). In Advanced Search, results are initially sorted in reverse chronological order (newest documents first). In Advanced Search, order by relevance is not available. The hits can be reorderd choosing sort options from a drop down menu.

Open Access Type

ZORA items having a full-text document are marked with a lock indicating its Open Access type:

Green Open Access

Green - refers to self-archiving generally the pre-print or post-print in repositories.

Gold Open Access

Gold - refers to publications in fully accessible Open Access journals or books.

Hybrid Open Access

Hybrid - also called Paid Open Access, refers to subscription journals with Open Access to individual articles usually when a fee is paid to the publisher or journal by the author, the author's organisation, or the research funder.

Closed Access: Download allowed only for UZH members

Closed or Embargoed Access: Download is allowed only for UZH members.

The Open Access type of ZORA items is determined either automatically, using various information sources such as the JDB, Directory of Open Access Journals, Unpaywall, and ZORA item information itself, or manually by the Open Access team of the Main Library of UZH. Note that the Open Access type is not a static quantity, but may change with time, e.g. if a publication flips from embargoed to Open Access.


ZORA integrates ORCID.
