28.1.3 Linking classification and text search
Classification codes were found for all aspects of the search question. As a plain classification search may lead to a
large number of hits (in particular in international databases) the search by classification should be linked to the
search by keywords. The various combinations of classification codes (IPC) and keywords should be considered, e.g.:
1. IPC (brakes for skates) AND Keywords (in-line skates)
2. IPC (in-line skates) AND Keywords (brakes)
3. IPC (brakes for skates) AND IPC (in-line skates)
4. Keywords (in-line skates) AND Keywords (brakes)
At last the individual results are combined by OR to form the overall result.
Combination (3) improves the overall result in particular for documents lacking text fields (e.g. utility models in
PATDPA, where there is neither an abstract nor a claim) while combination (4) yields an improved result with incomplete
or unfavourable classification.

fields are included, attributes are not used in this example, range searching)
