The Structured Search is another way to refine your search from the very start and gives you unique options for searching for text within specific fields of each document. Using the Structured Search tools, you can create specific search queries, filtering by dates, jurisdictions and document type. Also, alteration of default search parameters such as stemming, family grouping, query language and whether to only include documents with full text can be done. This search also allows you to limit your search terms to specific sections of documents. By searching for terms only within a given field, you can greatly reduce the number of extraneous results. For example, searching for an inventor’s name only within the Inventor field will eliminate documents that happen to mention the inventor in passing. With this search, you have the option to use the Boolean operator “AND” or “OR” between fields.
You can get to the Structured Search page at any time by clicking the “New Scholarly Search” button on the home page or on the dropdown menu next to the search button on the search results page. “New Structured Search” button is also available on the filter pane in each Lens page. Clicking on the button will led to the structured search page.
How to Use
In the query field you can choose which section of each scholarly document you would like your search terms applied to. You can choose between the sections: Lens ID, Title, Abstract, Indexed Full Text, Full Text, Date Published, Year Published, Publication Type, External Id Type, Author, Citation, Source, Subject Matter, Institution, Funding, Conferences, Clinical Trial, Open Access. You can add any number of these fields and combine them all using a Boolean AND or OR predicate. Hold CTRL/CMD to select multiple options from the auto-suggest list. Change the predicate to OR if results for all the options selected are wanted.
Selecting AND will mean a document must have at least one match for each term in the section it is being searched on to be added to the search results. Selecting OR will mean a document must have at least one of the terms matches in the section it is being searched on to be added to the search results.
Date Range (b)
You can use this section to search for only documents that were published or filed between a specific date range. You can select this date range using the in-built calendar or enter it in year-month-day format (eg. 1969-07-21).
ORCID LookUp Author (c)
Selecting an ORCID author and running the search will search for works in the Lens that are listed in the selected ORCID profile.
The flags section contains high level filters like “Is Open Access”, “Has Chemical”, “Has Funding”, “Has Clinical Trial” and many more.
Identifier Type (e)
You can use this section to limit your search to specific Identifier types. Identifier type includes
- Microsoft Academic
- PubMed Central
Publication Type (f)
