query
A keyword, group of keywords or phrase, with or without
special instructions like Boolean operators, used in a search.
In simpler terms, it is that which the user enters into
the search box. It is what the search engine compares documents
to in order to return only relevant documents.
query-by-example / find similar
Many search engines have a "find similar" feature
that allows users to request documents the search engine
considers similar to the document the user specifies.
query expansion / search within results
The process of basing a new query on an old one. Many search
engines allow users to "search within these results".
Additional Information:
The process of adding similar words to a query in such a
way that recall and precision improve. Expansion is done
mostly in the background using thesauri or other linguistic
resources.
quote(s)
When used in a search, the quote marks ' " ' tell most
systems that you only want to see matches that are exactly
like what you are asking for. For example, a search for
'electric light', entered without the single quotes, will
return much different results than "electric light"
entered with the quotes as shown.
