Member Function Documentation

◆ attach_files()

core_search\base::attach_files ( $document )

inherited

Files related to the current document are attached, to the document object ready for indexing by Global Search.

The default implementation retrieves all files for the file areas returned by get_search_fileareas(). If you need to filter files to specific items per file area, you will need to override this method and explicitly provide the items.

Parameters

document $document The current document

Return values

void

Reimplemented in core_search\base_activity, mod_forum\search\post, block_html\search\content, and mod_data\search\entry.

◆ check_access()

core_message\search\message_received::check_access ( $id )

Whether the user can access the document or not.

Parameters

int $id The message instance id.

Return values

int

Reimplemented from core_search\base.

◆ get_area_id()

core_search\base::get_area_id ( )

inherited

Returns the area id.

Return values

string

◆ get_category_names()

core_message\search\base_message::get_category_names ( )

inherited

Returns a list of category names associated with the area.

Return values

array

Reimplemented from core_search\base.

◆ get_component_name()

core_search\base::get_component_name ( )

inherited

Returns the moodle component name.

It might be the plugin name (whole frankenstyle name) or the core subsystem name.

Return values

string

Reimplemented in core_user\search\user, core_course\search\section, core_course\search\customfield, and core_course\search\course.

◆ get_component_type()

core_search\base::get_component_type ( )

inherited

Returns the component type.

It might be a plugintype or 'core' for core subsystems.

Return values

string

◆ get_config()

core_search\base::get_config ( )

inherited

Returns all the search area configuration.

Return values

array

◆ get_config_var_name()

core_search\base::get_config_var_name ( )

inherited

Returns the config var name.

It depends on whether it is a moodle subsystem or a plugin as plugin-related config should remain in their own scope.

Return values

string Config var path including the plugin (or component) and the varname

◆ get_context_url() [1/2]

core_message\search\base_message::get_context_url ( \core_search\document $doc )

inherited

Link to the conversation.

Parameters

core_search\document $doc

Return values

moodle_url

◆ get_context_url() [2/2]

core_search\base::get_context_url ( \core_search\document $doc )

abstractinherited

Returns a url to the document context.

Parameters

core_search\document $doc

Return values

moodle_url

Reimplemented in core_search\base_block, and core_search\base_activity.

◆ get_contexts_to_reindex()

core_search\base::get_contexts_to_reindex ( )

inherited

Gets a list of all contexts to reindex when reindexing this search area.

The list should be returned in an order that is likely to be suitable when reindexing, for example with newer contexts first.

The default implementation simply returns the system context, which will result in reindexing everything in normal date order (oldest first).

Return values

Iterator Iterator of contexts to reindex

Reimplemented in core_search\base_mod, and core_search\base_block.

◆ get_course_level_context_restriction_sql()

core_search\base::get_course_level_context_restriction_sql	(	\context	$context = `null`,
			$coursetable,
			$paramtype = `SQL_PARAMS_QM`
	)

protectedinherited

Helper function that gets SQL useful for restricting a search query given a passed-in context, for data stored at course level.

The SQL returned will be zero or more JOIN statements, surrounded by whitespace, which act as restrictions on the query based on the rows in a module table.

You can pass in a null or system context, which will both return an empty string and no params.

Returns an array with two nulls if there can be no results for a course within this context.

If named parameters are used, these will be named gclcrs0, gclcrs1, etc. The table aliases used in SQL also all begin with gclcrs, to avoid conflicts.

Parameters

context \| null	$context	Context to restrict the query
string	$coursetable	Name of alias for course table e.g. 'c'
int	$paramtype	Type of SQL parameters to use (default question mark)

Return values

array Array with SQL and parameters; both null if no need to query

Exceptions

coding_exception If called with invalid params

◆ get_recordset_by_timestamp()

core_search\base::get_recordset_by_timestamp ( $modifiedfrom = 0 )

inherited

Returns a recordset ordered by modification date ASC.

Each record can include any data self::get_document might need but it must:

Include an 'id' field: Unique identifier (in this area's scope) of a document to index in the search engine If the indexed content field can contain embedded files, the 'id' value should match the filearea itemid.
Only return data modified since $modifiedfrom, including $modifiedform to prevent some records from not being indexed (e.g. your-timemodified-fieldname >= $modifiedfrom)
Order the returned data by time modified in ascending order, as core_search::manager will need to store the modified time of the last indexed document.

Since Moodle 3.4, subclasses should instead implement get_document_recordset, which has an additional context parameter. This function continues to work for implementations which haven't been updated, or where the context parameter is not required.

Parameters

int $modifiedfrom

Return values

moodle_recordset

◆ get_search_fileareas()

Return values

◆ supports_get_document_recordset()

core_search\base::supports_get_document_recordset ( )

inherited

Checks if get_document_recordset is supported for this search area.

For many uses you can simply call get_document_recordset and see if it returns false, but this function is useful when you don't want to actually call the function right away.

core_search\base::uses_file_indexing ( )

inherited

Returns true if this area uses file indexing.
