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:
“To the horror of all who were present that day,
He uprose in full evening dress,
And with senseless grimaces endeavoured to say
What his tongue could no longer express.”

“I would define the poetic effect as the capacity that a text displays for continuing to generate different readings, without ever being completely consumed.”

Do our black faces search the empty sky?
Is there something we have forgotten? some precious thing
We have lost, wandering in strange lands?”
