Of course, the premise of using Google Scholarship is that you can seamlessly access Google's services. Although it is well known that there are incisive and detailed answers to the relevant questions, do this repetitive work for the convenience of others. Google academic suitable for what kind of document retrieval needs. To obtain a preliminary or exploratory inquiry into the relevant field of literature query author/Researcher's related literature Quick Find a small number of related literature to find the citation frequency: also contains references for other than peer-reviewed literature, such as dissertations looking for a document with associated articles subscribing to the researcher's new literature ... Google Scholarship is not suitable for what kind of literature search. Systematic document retrieval: For example, the literature retrieval needed in the writing meta analysis and the review the results of citation query are statistically analyzed according to the full text of the unpublished literature of the Organization's retrieval literature. How to identify keywords

The keywords used in the search are generally notional. In order to improve the efficiency of retrieval, we must determine the key words before searching, and do not use "sentences" to retrieve them directly. Before identifying the key words, please consider synonyms and part of the speech problem. Although Google Scholarship will help you develop synonyms and parts of speech, forming such information retrieval ideas in your mind can help you get information. Brainstorming on draft paper helps to identify keywords. General Search

The general search directly input keywords on it. This kind of retrieval is relatively simple, suitable for exploratory search, that is, no specific purpose, only rough access to information. However, it is inefficient to obtain information through this retrieval method. It is recommended that you use qualifiers and identifiers for retrieval. In general search, the search engine defaults to a space-delimited word as a condition that needs to be met (that is, "and"). For example:

Emotion regulation equal to emotion+regulation or emotion and regulation

Advanced Search

Advanced search can be opened by clicking the Inverted triangle button to the right of the searching box. How to locate the author. The English literature uses the Latin alphabet, the Chinese literature use Chinese can use the full name, also may use abbreviation, the full name is more accurate, the abbreviation is more vague. Note that the name of the foreigner also includes middle name, so it is necessary to consider middle name to make the retrieval more accurate. Use double quotes (English half-width quotes) including names:

Author: "James Gross"
Author: "J Gross"
Author: "JJ Gross"
Author: ("JJ Gross" OR "James Gross")

Or use Search options manually: The inverted triangle button on the right side of the search box defines the title.

Intitle: "Emotion regulation"
intitle: ("Emotion regulation" and "Emotion dysregulation")
intitle: ((Emotion OR Mood or affect) and (regulation or dysregulation))

How to qualify periodicals.

Google Scholarship does not have a qualifying term for a journal, but it can be retrieved in the Advanced search box by entering a corresponding journal entry in a journal input box. Use double quotes to wrap journal names when you need to retrieve multiple journals, using OR logical characters to separate multiple journal names wrapped in double quotes. For example:

"Emotion" OR "cognition and Emotion"

or enter in the direct search box

("Emotion" OR "cognition and Emotion")

But this is often inaccurate because it matches the field in any location. You can also query the parameters of the journal by adding them to the URL:

https://scholar.google.com/scholar?hl=en&q=key+words&as_publication= "Journal+of+one+field" +or+ "journal +of+other+fields "

&as_publication= is the designated periodical.
How to exclude keywords.

Use a minus sign to emit a given keyword:

Intitle: (Emotion-mood)

At this point, only the results that contain the emotion are displayed, not the results of the title containing the mood how to qualify the year directly by selecting the year option from the left column. Enter year retrieval in the search box (not recommended). How to retrieve multiple, parallel keywords

Use OR () to build multiple parallel search terms, such as:

(emotion or mood or affect)

Or

("Emotion regulation" or "affect regulation" or "Emotion Control")

In fact, this time does not need () to include, but also effective. How to use and logical characters

And you can set keywords that must appear, plus OR you can do more powerful searches. For example:

(emotion or mood or affect) and (ERP or EEG or Meg or fMRI or "functional MRI")

How to qualify documents that support full-text access if the PDF does not appear on the right side of the entry, do not think there is no full-text link. Click to enter all n version links to see if there is a full-text link. Restrict only entries that can get the full text:

Filetype:pdf

Filetype:pdf (emotion and mood and affect)

Finally, a more complicated example

Filetype:pdf 2015 (intitle: "Emotion regulation" or intitle: "Emotion Control" or intitle: "Cognitive reappraisal" or intitl E: "Emotion Suppression") and (Intitle:erp or Intitle:eeg or Intitle:meg or Intile:fmri or intitle: "Functional MRI" or inti Tle:electroencephalography or intitle: "Event related potential" or intitle:magnetoencephalography)

When I went to retrieve this, I found an error, and the field of the search box was automatically truncated. I counted the number of characters and found the remaining 256 characters. This indicates that the character length of the retrieval criteria is limited. This also shows that Google Scholarship only provides a limited search function.

Streamline:

Filetype:pdf intitle: ("regulation" OR "control") and Intitle:emotion and (ERP or EEG or Meg or fMRI or "functional MRI" or Electroencephalography or "event related potential" or magnetoencephalography)

To sum up, combine these special symbols: "", (), or, and, intitle:, Author: You can combine various retrieval conditions. Of course, it is not good to try to know.
