WARNING
|
|
-------
|
|
|
|
This implementation of full text indexing is very slow and inefficient. It is
|
|
STRONGLY recommended that you switch to using contrib/tsearch which offers these
|
|
features:
|
|
|
|
Advantages
|
|
----------
|
|
* Actively developed and improved
|
|
* Tight integration with OpenFTS (openfts.sourceforge.net)
|
|
* Orders of magnitude faster (eg. 300 times faster for two keyword search)
|
|
* No extra tables or multi-way joins required
|
|
* Select syntax allows easy 'and'ing, 'or'ing and 'not'ing of keywords
|
|
* Built-in stemmer with customisable dictionaries (ie. searching for 'jellies' will find 'jelly')
|
|
* Stop words automatically ignored
|
|
* Supports non-C locales
|
|
|
|
Disadvantages
|
|
-------------
|
|
* Only indexes full words - substring searches on words won't work.
|
|
eg. Searching for 'burg' won't find 'burger'
|
|

|
Due to the deficiencies in this module, it is quite likely that it will be removed from the standard PostgreSQL distribution in the future.
