In the Mendeley Data homepage, use the “Find Research Data” box to enter keywords and perform a simple search. If you want, you can perform an advanced search using a targeter and / or boolean operators. See “How can I perform an advanced search?” for more details.

In the Mendeley Data homepage, use the “Find Research Data” to perform an advanced search. The syntax works by using field codes to target one or more specific fields, and is used as follows:

- AUTHOR()
- AUTHOR_ID()
- TITLE()
- INSTITUTION()
- INSTITUTION_ID()
- ID()
- DOI()
- KEYWORDS()
- SUBJECT_AREA()
- IS_SUPPLEMENT_TO()

AUTHOR_ID() supports the following IDs: Mendeley User ID, Scopus User ID, ORCID and all user IDs supported by DataCite.

INSTITUTION_ID() supports the following IDs: Scopus Institution ID, Scival Institution ID, Mendeley Institution ID.

Additionally DataSearch supports Boolean search terms. You may search for data on DataSearch using AND, OR or NOT query terms.

Field codes can also be used in any boolean query, which includes OR between normal and field code queries.

Currently DataSearch can process queries like these:

- chip-seq drosophila AUTHOR(Doe)
- chip-seq drosophila AUTHOR(Doe OR Hari)
- chip-seq drosophila AUTHOR(Hari) AND INSTITUTION(University of Manchester)
- chip-seq AND (drosophila OR “fruit fly”) AND ID(GEO4667)
- (chip-seq drosophila AND AUTHOR(Doe)) OR AUTHOR(Doe AND Hari)
- IS_SUPPLEMENT_TO(10.1016/j.dib.2015.10.003)

When no operator is included this is assumed to be an implicit OR'. If you want to perform an exact match of the text being provided by a Field Code, you can use Field Code modifiers. We offer two ways to do it:

- FIELD CODE(“abcdfg”)
- FIELD CODE({abcdfg})

Operators (AND, OR and NOT) are not recognised inside a Field Code modifier. As such, queries using FIELD CODE(“xxxx OR yyyy”) will probably not retrieve the results one would expect. There are three ways to use operators inside a targeter:

- Using a Field Code (without any modifiers): AUTHOR(John OR Martha)
- Splitting the operands into separate Field Codes with modifiers: AUTHOR({John}) OR AUTHOR({Martha})
- Using double quotes in a targeter modifier - this is accepted in order to provide backwards compatibility to very common queries that might have been used extensibly: INSTITUTION(“University of Manchester” OR “University of Oxford”)
Note: INSTITUTION({University of Manchester} OR {University of Oxford}) is not accepted! Use INSTITUTION({University of Manchester}) OR INSTITUTION({University of Oxford}) instead.

It should be noted that using the “xxxx” construct (i.e. using double quotes to specify an exact text match in a search) is also allowed outside a Field Code. The behaviour for such a query is expected: all the words are inside the double quotes are searched as they appear. On the other hand, the {xxxx} construct ((i.e. using curly braces to specify an exact text match in a search) is only accepted as a Field Code modifier and is not accepted in a free text search (as curly braces are not accepted characters for free text search).

To conclude, here are some simple examples:

- AUTHOR(“John Doe”) - will search for authors whose names have exactly the words John followed by Doe in any part of their names.
- DOI({123456:1132/121(56)789}) - will search for the document that has a 123456:1132/121(56)789 DOI identifier.
- ID(“1234.1224”) - will search for the document that has a 1234.1224 external identifier.
- AUTHOR({John Doe OR Martha Hari}) - will search for authors whose names are John Doe OR Martha Hari in any part of their names (probably not finding anything).
- AUTHOR({John Doe}) OR AUTHOR(“Martha Hari”) - will search for authors whose names have either the sequence John Doe or Martha Hari in any part of their names.
