Search Result Highlighting

VuFind supports highlighting in all of its current search modules, but the details are slightly different for each search platform.

Solr

VuFind's main Solr-based search has customizable highlighting features controlled by the highlighting setting in searches.ini. The related snippets setting and [Snippets_Captions] section may be used to control the display of highlighted text snippets when matches are found outside of the fields normally displayed by default as part of a search result.

Technical Details

If more advanced customization is needed, note that a lot of the highlighting behavior is controlled by the \VuFind\RecordDriver\SolrDefault record driver, with some low-level pieces embedded in the Search system.

Further Reading

The Solr highlighting documentation provides some information on what is possible.

For more technical details on VuFind's highlighting implementation (now significantly outdated), see this blog post from 2011.

Sharing Enhancements

If you add any significant features to your local VuFind instance, please consider sharing them in JIRA for inclusion in future releases of VuFind – there is definitely a potential for additional highlighting-related configuration options.

Summon

Highlighting in the Summon module is slightly less flexible than Solr highlighting, but it works very similarly, using the highlighting and snippets settings found in Summon.ini.

WorldCat

VuFind's WorldCat module does not currently support highlighting. The feature was dropped in release 2.0 in the interest of simplifying the code. If you need this capability, please vote on the VUFIND-640 JIRA ticket so it can be prioritized appropriately.
