CLAIMS Direct is a web service that provides access to the IFI CLAIMS Global Patent Database, a Data Warehouse that contains patent records from over 90 patenting authorities stored in a common XML format. Each publication, including all published applications and granted patents, is represented by a separate record in the data.

The SOLR index supports AND, OR, and NOT as Boolean operators. Boolean operators must be ALL CAPS. If you enter these operators in lower case letters, the system will search them as terms.
AND
The AND operator matches documents where both terms exist anywhere in the text of a single document. This is equivalent to an intersection using sets. For example, to search for documents that contain "solar energy" and "heating," use the following query:
| "solar energy" AND heating |
NOT
The NOT operator excludes documents that contain the term after NOT. This is equivalent to a difference using sets. The symbol "!" can be used in place of the word NOT. For example, to search for documents that contain "solar energy" but not "heating" use the following query:
| "solar energy" NOT heating |
OR
The OR operator links two terms and finds a matching document if either of the terms exist in a document. This is equivalent to a union using sets. The symbol || can be used in place of the word OR.
For example, to search for documents that contain either "solar energy" or "wind power," use the following query:
| "solar energy" OR "wind power |

Default Operator
In CLAIMS DIrect, the default operator is AND. This means that if no operator is specified, the system assumes AND. In the above examples, we explicitly included the operator in all cases for purposes of clarity.

Note: You must enter Operators in ALL CAPS and enter field names in lower case.

Searches in CLAIMS SOLR can include multiple search fields and multiple criteria per field. A few examples are provided to illustrate these more complex queries. Please consult the table at the end of this document for descriptions and additional search examples on a field-by-field basis.
