This filter allows free text search in both the title and the abstract of the article. If a certain expression is put in quotation marks, it must appear as written in the text.

This filter allows you to search for articles published in journals classified in a certain quartile by the value of the impact factor of that journal. The Clarivate Journal Citation Report is used as a data source.

This filter allows you to search for articles published in journals classified in the first decile by the value of the impact factor of that journal. The Clarivate Journal Citation Report is used as a data source.

The categories of the Web of Science are used to classify the journals. You can filter using one or more of these scientific categories to filter articles by the subject matter of the journal in which they are published.

In this filter you must enter the symbol of the genes you are interested in searching for. In addition to searching by the symbol, it also filters by all the aliases that the gene has available in the NCBI gene database. Genes must be separated by spaces, lines, commas or semicolons.

With this filter you can search for articles published in journals with an impact factor equal to or greater than that indicated by the user. The Clarivate Journal Citation Report has been used as a source for this data.

The user can delimit the years of publication of the articles. The date of registration in PubMed is used as the date of publication.

With this filter you can search for articles that have a number of cites greater than or equal to that indicated by the user. The Web of Science has been used as a source of cites.

This component requires the user to enter at least three characters of the search term. As you continue to type the component, it recommends the items that should be used in the search. This component is used in several filters:

1. Journals. Filter by the name of the journal where the article has been published.
2. Authors. Filter by the full name of the author of the article.
3. Organizations. Filter by the affiliation organization name of the authors of the article. The source of this information comes from Web of Science.
4. Diseases. Use the description and synonyms of the MESH database in your disease taxonomy.
5. Chemicals. Uses the description and synonyms of the MESH database in its taxonomy of chemicals and drugs.
6. Pharmacological Actions. Uses the description and synonyms of the MESH database in its taxonomy of pharmacological actions. In this case, the search engine will use as a search mechanism, in addition to the pharmacological action itself, those drugs that have that action.
7. Species. It uses the scientific name or the synonyms of the NCBI species taxonomy.

The user always has to select one of the items proposed by the search component. You cannot search by free text!

This component allows you to filter by selecting one or more items from the list it displays. The search fields that use this filter are

1. Countries. Allows you to filter by the countries of origin of the authors of the publication.
2. Publication types. Allows to include or exclude the types of article defined by Pubmed.

The Human Phenotype Ontology (HPO) is used to perform this filter. It can be filtered using one or more phenotypes, and what the search engine will do is to search for articles by the genes involved in those phenotypes.

The KEGG metabolic pathways database is used to perform this filter. It can be filtered using one or more metabolic pathways, and what the search engine will do is to search for articles by the genes involved in those pathways.

Using this filter, the search fields of that section only use the title and the summary to make the search. If it is not used, they search all available text in the article.
