“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.”
