Faceting in Solr 1.4 Enterprise Search Server

"Moreover, in addition, it can power term-suggest aka auto-complete functionality, which enables your search application to suggest a completed word that the user is typing, which is based on the most commonly occurring words starting with what they have already typed. So if a user started typing siamese dr, then Solr might suggest that dreams is the most likely word, along with other alternatives.

"Faceting, sometimes referred to as faceted navigation, is usually used to power user interfaces that display this summary information with clickable links that apply Solr filter queries to a subsequent search.

"If we revisit the comparison of search technology to databases, then faceting is more or less analogous to SQL's group by feature on a column with count(*). However, in Solr, facet processing is performed subsequent to an existing search as part of a single request-response with both the primary search results and the faceting results coming back together. In SQL, you would need to potentially perform a series of separate queries to get the same information."
