In text retrieval, full text search refers to techniques for searching a single computer-stored document or a collection in a full text database. Full text search is distinguished from searches based on metadata or on parts of the original texts represented in databases (such as titles, abstracts, selected sections, or bibliographical references).
In a full text search, the search engine examines all of the words in every stored document as it tries to match search criteria (e.g., words supplied by a user). Full text searching techniques became common in online bibliographic databases in the 1990s. Many web sites and application programs (such as word processing software) provide full-text search capabilities. Some web search engines such as AltaVista employ full text search techniques while others index only a portion of the web pages examined by its indexing system.

Famous quotes containing the words full, text and/or search:
“Language was not powerful enough to describe the infant phenomenon. Ill tell you what, sir, he said; the talent of this child is not to be imagined. She must be seen, sirseento be ever so faintly appreciated.... The infant phenomenon, though of short stature, had a comparatively aged countenance, and had moreover been precisely the same agenot perhaps to the full extent of the memory of the oldest inhabitant, but certainly for five good years.”
—Charles Dickens (18121870)
“If ever I should condescend to prose,
Ill write poetical commandments, which
Shall supersede beyond all doubt all those
That went before; in these I shall enrich
My text with many things that no one knows,
And carry precept to the highest pitch:
Ill call the work Longinus oer a Bottle,
Or, Every Poet his own Aristotle.”
—George Gordon Noel Byron (17881824)
“Gaily bedight,
A gallant knight,
In sunshine and in shadow,
Had journeyed long,
Singing a song,
In search of Eldorado.”
—Edgar Allan Poe (18091849)
