CERN Search Syntax Summary

  Dariusz Kogut IT/WO

A new online help page has been prepared for the InfoSeek Search Engine (see the article "Search Engine News" in this CNL). This page,
is based on CERN Intranet examples and has improved help for syntax issues.

InfoSeek will find documents containing as many of these words and phrases as possible, ranked so that the documents most relevant to your query are presented first. The syntax of this Search Engine is summarized in the following table.

Specifies that words should be adjacent. 
"scientific committees"   returns all pages containing those words next to each other.
+term Requires a term. 
+microcosm +exhibition  returns all pages with both microcosm and exhibition, but not necessarily next to each other.
 term1 AND term2
