The correct answer is "Advanced Search" because it allows the user to search for specific fields, construct a multi-concept search strategy, and limit the retrieval by various criteria such as region, subregion, country, language, publication year, and POPLINE Document Number. This option provides more advanced search capabilities compared to the other options mentioned.

The correct answer is TRUE - at least the first 3 characters. This means that when using an asterisk (*) as a wildcard to truncate a word, we need to type at least the first 3 characters of the word before the asterisk. For example, if we want to search for words like report, reports, or reporter, we can type "report*".

The correct answer is "Box 'Advanced Search' of Google Scholar" because Google Scholar provides an advanced search option that allows users to refine their search queries by specifying specific criteria such as author, publication, date, and keywords. This feature helps users to narrow down their search results and find more relevant and specific information.

Pubmed provides filters for searching articles based on various criteria such as sex, languages, and type of articles. However, it does not have a specific filter for searching articles based on affiliation country. This means that users cannot directly filter articles based on the country of the affiliations of the authors.

The statement is true because when searching for "obesity" AND "treatment" in Pubmed, the results will include all articles that mention both terms individually, as well as articles that specifically discuss the treatment of obesity. On the other hand, searching for "obesity treatment" will only retrieve articles that specifically mention this exact phrase. Therefore, the results for the first search will be larger than the results for the second search.

The explanation for the given correct answer is that when searching with ISI (Web of Science), the system does not differentiate between lowercase and uppercase letters. This means that the search is not case sensitive, and the keywords entered will be searched in the title, abstract, and keyword fields only.

The components of a well-specific research question include the population being studied, the intervention or exposure being investigated, the comparison group(s) being used, and the outcome(s) being measured. These components are essential for designing a research study that is focused and can generate meaningful results. The answer "Population, Intervention/exposure, Comparison group(s), outcome(s)" includes all these necessary components.

Boolean logics cannot be used in NYAM.

Scopus allows users to perform Boolean searching, which means they can use operators such as AND, OR, and NOT to combine or exclude search terms. This allows for more precise and targeted search results. Therefore, the statement that Boolean searching is not available in Scopus is incorrect.

DOI stands for Digital Object Identifier, which is a unique alphanumeric string assigned to a digital object or document. It is used to provide a persistent link to the content, ensuring that it can be easily and reliably located on the internet. The DOI system is widely used across various domains, including academic publishing, to ensure the long-term accessibility and citability of digital resources. Therefore, the correct answer is "DOI is a digital identifier used to uniquely identify an object/document in the internet."

The symbol "$" can be used when searching for words with the same root in VHL. This symbol is commonly used as a wildcard to represent any number of characters in a search term. So, by using "$" in a search query, it will retrieve all the words that have the same root as the specified term, such as economy, economist, and economical.

The correct answer is (1) OR - (2) OR - (3) AND. When searching with POPLINE, if multiple words are entered without a Boolean operator, the default is to search for all the words using the OR operator. This means that the search will return results that include any of the entered words. In this case, "family planning" will search for "family" OR "planning", not "family" AND "planning".

The symbol "?" can be used to replace character variation in the middle of a word while searching using VHL. This symbol acts as a wildcard and can represent any single character. Therefore, if we use "?" in the search term "organi?ation", it will match both "organiZation" and "organiSation".

The correct answer is (1) AND - (2) AND. When searching with SIGLE, the implicit operator used between different words typed in the same field is "AND". This means that all the words in the search query must be present in the search results. Similarly, the default operator between different fields in an advanced search is also "AND". This means that the search results must contain all the specified words in each field.

The statement states that after searching with NYAM, we can limit our search results manually but not automatically. This means that while we can manually narrow down our search results using NYAM, we cannot do so automatically. Therefore, the correct answer is FALSE, as it contradicts the statement.

The h-index is a measure of a scientist or scholar's productivity and citation impact. It is based on the number of citations their most cited papers have received in other publications. In this case, the answer is 88 because it is the highest number in the given set of documents.
