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

fields are included, attributes are not used in this example, range searching)<br />
