Citation Recognition 

JustCite makes use of Justis Publishing’s citation recognition technology, the JustCite Reference Recognition Engine, or JRRE (pron. “Jerry”) for short.

JRRE is the technology behind JustCite’s “friendly” citation searching whereby a syntactically defective citation search nevertheless succeeds. It also powers JustCite’s common name search, as well as JustCite’s sister product, JustCite for Word.

For example, a search for 2011 2 wlr 36 will automatically be converted by JRRE into [2011] 2 WLR 36, and a search for whiter shade of pale case will be converted to [2009] 1 WLR 1764.

To that end, JRRE is called very early on in the search process. If JRRE finds a citation in the search terms it takes over the search completely; the rest of the JustCite search chain is not run. Instead, the document with the matching citation, or the documents matching the partial citation, are displayed immediately.

A necessary consequence of this behaviour is that, in the general search box, any other search terms will be ignored once JRRE is engaged. If you want to combine a partial citation with other search terms, you must therefore use the Advanced Search, which will work because only the Citation/Reference fields are passed to JRRE.

TIP: It is possible to force JustCite to omit JRRE from the search chain by enclosing one or more of your search terms in double quotation marks. For instance, the search terms nitrates directive will be converted by JRRE to 31991L0676, because ‘Nitrates Directive’ is a common name for Directive 91/676/EEC. However, the search terms "nitrates" directive will force JustCite to omit JRRE and instead a simple AND search for those two terms will be performed.
