Detailed Description

Service to manage and access search profiles.

Search profiles are arranged by type identified by a string constant:

COMPLETION: profiles used for autocomplete search when running the completion suggester
CROSS_PROJECT_BLOCK_SCORER: used when reordering blocks of crossproject search results
FT_QUERY_BUILDER: used when building fulltext search queries
PHRASE_SUGGESTER: Controls the behavior of the phrase suggester (did you mean suggestions)
INDEX_LOOKUP_FALLBACK: Controls the behavior of the index lookup fallback method (did you mean suggestions)
RESCORE: Controls how elasticsearch rescore queries are built
RESCORE_FUNCTION_CHAINS: Controls the list of functions used by a rescore profile
SANEITIZER: Controls the saneitizer
SIMILARITY: Defines similarity profiles used when building the index

Multiple repository per type can be declared, in general we have:

the cirrus_base repository holding the default profiles contained in cirrus code
the cirrus_config repository holding the profiles customized using $wgCirrusSearch config vars.

The service is bound to a SearchConfig instance which means that the profiles may vary depending on the SearchConfig being used. The cirrus_base repository will always hold the same set of profiles but the cirrus_config may change according to SearchConfig content.

The service is also responsible for determining the name of the default profile for a given context. The profile context is a notion introduced to allow using the same profile for multiple purposes. For example the rescore profiles may be used for different kind of queries (fulltext vs prefixsearch). While they share the same set of profiles we may prefer to use different defaults depending on the type of the query. The profile context allows to distinguish between these use cases.

Then in order to customize the default profile the service allows to define a list of "overriders":

ConfigSearchProfileOverride: overrides the default profile by reading a config var
UriParamSearchProfileOverride: overrides the default profile by inspecting the URI params
UserPrefSearchProfileOverride: overrides the default profile by inspecting the user prefs

Member Function Documentation

◆ getDispatchService()

CirrusSearch\Profile\SearchProfileService::getDispatchService ( )

Return the service responsible for dispatching a SearchQuery to its preferred profile context.

Returns: SearchQueryDispatchService

◆ getProfileName()

CirrusSearch\Profile\SearchProfileService::getProfileName	(		$type,
			$context = self::CONTEXT_DEFAULT,
		array	$contextParams = [] )

Parameters

string	$type	the type of the profile (see class doc)
string	$context
string[]	$contextParams	Parameters of the context, for determining the profile name. Some overriders use these to decide if an override is appropriate.

Returns: string

◆ hasProfile()

CirrusSearch\Profile\SearchProfileService::hasProfile	(		$type,
			$name )

Parameters

string	$type
string	$name

Returns: bool

◆ listExposedProfiles()

CirrusSearch\Profile\SearchProfileService::listExposedProfiles ( $type )

List profiles under type $type that are suited to be exposed to the users.

This method is provided for convenience and to help users to discover existing profile. It's possible that an existing profile may not be listed here so this method must not be used to verify the existence of a given profile. Use hasProfile instead.

Parameters

string $type

Returns: array

◆ listProfileContexts()

CirrusSearch\Profile\SearchProfileService::listProfileContexts ( $type )

List default profile per context.

Parameters

string $type

Returns: string[] context is the key, the default profile name

◆ listProfileOverrides()

CirrusSearch\Profile\SearchProfileService::listProfileOverrides	(		$type,
			$context )

L.

Parameters

string	$type
string	$context

Returns: SearchProfileOverride[]

◆ listProfileRepositories()

CirrusSearch\Profile\SearchProfileService::listProfileRepositories ( $type )

List profile repositories.

Parameters

string $type

Returns: SearchProfileRepository[]

◆ listProfileTypes()

CirrusSearch\Profile\SearchProfileService::listProfileTypes ( )

Returns: string[]

◆ loadProfile()

CirrusSearch\Profile\SearchProfileService::loadProfile	(	$type,
		$context = self::CONTEXT_DEFAULT,
		$name = null,
		$contextParams = [] )

Load a profile for the context or by its name if name is provided.

Parameters

string	$type
string	$context	used to determine the name of the profile if $name is not provided
string \| null	$name	force the name of the profile to use
string[]	$contextParams	Parameters of the context, for determining the profile name. Some overriders use these to decide if an override is appropriate.

Returns: array

See also: self::getProfileName()

◆ loadProfileByName()

CirrusSearch\Profile\SearchProfileService::loadProfileByName	(	$type,
		$name,
		$failIfMissing = true )

Load a profile by its name.

It's better to use self::loadProfile and let the service determine the proper profile to use in a given context.

Parameters

string	$type	the type of the profile (see class doc)
string	$name
bool	$failIfMissing	when true will throw SearchProfileException

Returns: array|null
