PHPXRef 0.7.1 : phpBB-3.3.14-deutsch : Detail view of fulltext

Fulltext search based on the sphinx search daemon

__construct(&$error, $phpbb_root_path, $phpEx, $auth, $config, $db, $user, $phpbb_dispatcher) X-Ref

Constructor
Creates a new \phpbb\search\fulltext_postgres, which is used as a search backend

param: string|bool $error Any error that occurs is passed on through this reference variable otherwise false
param: string $phpbb_root_path Relative path to phpBB root
param: string $phpEx PHP file extension
param: \phpbb\auth\auth $auth Auth object
param: \phpbb\config\config $config Config object
param: \phpbb\db\driver\driver_interface $db Database object
param: \phpbb\user $user User object
param: \phpbb\event\dispatcher_interface $phpbb_dispatcher Event dispatcher object

get_name() X-Ref

Returns the name of this search backend to be displayed to administrators

return: string Name

get_search_query() X-Ref

Returns the search_query

return: string search query

get_word_length() X-Ref

Returns false as there is no word_len array

return: false

get_common_words() X-Ref

Returns an empty array as there are no common_words

return: array common words that are ignored by search backend

init() X-Ref

Checks permissions and paths, if everything is correct it generates the config file

return: string|bool Language key of the error/incompatibility encountered, or false if successful

config_generate() X-Ref

Generates content of sphinx.conf

return: bool True if sphinx.conf content is correctly generated, false otherwise

split_keywords(&$keywords, $terms) X-Ref

Splits keywords entered by a user into an array of words stored in $this->split_words
Stores the tidied search query in $this->search_query

param: string $keywords Contains the keyword as entered by the user
param: string $terms is either 'all' or 'any'
return: false if no valid keywords were found and otherwise true

sphinx_clean_search_string($search_string) X-Ref

Cleans search query passed into Sphinx search engine, as follows:
1. Hyphenated words are replaced with keyword search for either the exact phrase with spaces
or as a single word without spaces eg search for "know-it-all" becomes ("know it all"|"knowitall*")
2. Words with apostrophes are contracted eg "it's" becomes "its"
3. <, >, " and & are decoded from HTML entities.
4. Following special characters used as search operators in Sphinx are preserved when used with correct syntax:
(a) quorum matching: "the world is a wonderful place"/3
Finds 3 of the words within the phrase. Number must be between 1 and 9.
(b) proximity search: "hello world"~10
Finds hello and world within 10 words of each other. Number can be between 1 and 99.
(c) strict word order: aaa << bbb << ccc
Finds "aaa" only where it appears before "bbb" and only where "bbb" appears before "ccc".
(d) exact match operator: if lemmatizer or stemming enabled,
search will find exact match only and ignore other grammatical forms of the same word stem.
eg. raining =cats and =dogs
will not return "raining cat and dog"
eg. ="search this exact phrase"
will not return "searched this exact phrase", "searching these exact phrases".
5. Special characters /, ~, << and = not complying with the correct syntax
and other reserved operators are escaped and searched literally.
Special characters not explicitly listed in charset_table or blend_chars in sphinx.conf
will not be indexed and keywords containing them will be ignored by Sphinx.
By default, only $, %, & and @ characters are indexed and searchable.
String transformation is in backend only and not visible to the end user
nor reflected in the results page URL or keyword highlighting.
