+trgm - Trigram matching for PostgreSQL
+--------------------------------------
+
+Introduction
+
+ This module is sponsored by Delta-Soft Ltd., Moscow, Russia.
+
+ The pg_trgm contrib module provides functions and index classes
+ for determining the similarity of text based on trigram
+ matching.
+
+Definitions
+
+ Trigram (or Trigraph)
+
+ A trigram is a set of three consecutive characters taken
+ from a string. A string is considered to have two spaces
+ prefixed and one space suffixed when determining the set
+ of trigrams that comprise the string.
+
+ eg. The set of trigrams in the word "cat" is " c", " ca",
+ "at " and "cat".
+
+Public Functions
+
+ real similarity(text, text)
+
+ Returns a number that indicates how closely matches the two
+ arguments are. A zero result indicates that the two words
+ are completely dissimilar, and a result of one indicates that
+ the two words are identical.
+
+ real show_limit()
+
+ Returns the current similarity threshold used by the '%'
+ operator. This in effect sets the minimum similarity between
+ two words in order that they be considered similar enough to
+ be misspellings of each other, for example.
+
+ real set_limit(real)
+
+ Sets the current similarity threshold that is used by the '%'
+ operator, and is returned by the show_limit() function.
+
+ text[] show_trgm(text)
+
+ Returns an array of all the trigrams of the supplied text
+ parameter.
+
+Public Operators
+
+ text % text (returns boolean)
+
+ The '%' operator returns TRUE if its two arguments have a similarity
+ that is greater than the similarity threshold set by set_limit(). It
+ will return FALSE if the similarity is less than the current
+ threshold.
+
+Public Index Operator Classes
+
+ gist_trgm_ops
+
+ The pg_trgm module comes with an index operator class that allows a
+ developer to create an index over a text column for the purpose
+ of very fast similarity searches.
+
+ To use this index, the '%' operator must be used and an appropriate
+ similarity threshold for the application must be set.
+
+ eg.
+
+ CREATE TABLE test_trgm (t text);
+ CREATE INDEX trgm_idx ON test_trgm USING gist (t gist_trgm_ops);
+
+ At this point, you will have an index on the t text column that you
+ can use for similarity searching.
+
+ eg.
+
+ SELECT
+ t,
+ similarity(t, 'word') AS sml
+ FROM
+ test_trgm
+ WHERE
+ t % 'word'
+ ORDER BY
+ sml DESC, t;
+
+ This will return all values in the text column that are sufficiently
+ similar to 'word', sorted from best match to worst. The index will
+ be used to make this a fast operation over very large data sets.
+
+Tsearch2 Integration
+
+ Trigram matching is a very useful tool when used in conjunction
+ with a text index created by the Tsearch2 contrib module. (See
+ contrib/tsearch2)
+
+ The first step is to generate an auxiliary table containing all
+ the unique words in the Tsearch2 index:
+
+ CREATE TABLE words AS
+ SELECT word FROM stat('SELECT vector FROM documents');
+
+ Where 'documents' is the table that contains the Tsearch2 index
+ column 'vector', of type 'tsvector'.
+
+ Next, create a trigram index on the word column:
+
+ CREATE INDEX words_idx ON words USING gist(word gist_trgm_ops);
+
+ Now, a SELECT query similar to the example above can be used to
+ suggest spellings for misspelled words in user search terms. A
+ useful extra clause is to ensure that the similar words are also
+ of similar length to the misspelled word.
+
+ Note: Since the 'words' table has been generated as a separate,
+ static table, it will need to be periodically regenerated so that
+ it remains up to date with the word list in the Tsearch2 index.
