Search for keyword(s)
The Search for keyword(s) field isused to search for a term against the full text sections of a patent. Used in combination with the In doc sections checkboxes, the keyword search may be restricted to a specific full text section.
Note: See Document Section Filter for an explanation of the keyword searchable document sections.
There are two types of terms: words and phrases. A “word” is a continuous string of characters without any spacing, such as "gleevec" or "kinase."
A phrase is a group of words treated as an individual unit. To locate the phrase exactly as it is written, the phrase must be surrounded by double quotes.
Boolean operators are used within the keyword search to combine separate terms into a single complex query. SureChEMBL uses three Boolean operators: AND, OR, and NOT.
|AND||Intersection: For an individual document to be included in the results set, it must contain both of the individual query elements.|
|OR||Union: For an individual document to be included in the results set, it only has to contain one of the individual query elements.|
|NOT||Difference: For an individual document to be included in the results set, it must contain the first listed individual query element and must not contain the second.|
Note: The Boolean operators must ALWAYS be written in uppercase.
The default Boolean operator for SureChEMBL is AND. If you enter two word into a query field without quotes or any operator, the application will return all documents containing both terms. The terms will not necessarily appear immediately adjacent to one another.
Note: The query may include the combination of your keyword(s) AND additional bibliographic field search definitions. See Bibliographic Search Definition for an explanation of including bibliographic field search definitions.
