Constructor & Destructor Documentation

◆ __construct()

core_search\document::__construct (   $itemid,
  $componentname,
  $areaname 
)

We ensure that the document has a unique id across search areas.

Parameters
int$itemidAn id unique to the search area
string$componentnameThe search area component Frankenstyle name
string$areanameThe area name (the search area class name)
Return values
void

Member Function Documentation

◆ add_stored_file()

core_search\document::add_stored_file (   $file)

Add a stored file to the document.

Parameters
stored_file | int$fileThe file to add, or file id.
Return values
void

◆ apply_defaults()

core_search\document::apply_defaults ( )
protected

Apply any defaults to unset fields before export.

Called after document building, but before export.

Sub-classes of this should make sure to call parent::apply_defaults().

Reimplemented in search_solr\document.

◆ export_for_engine()

core_search\document::export_for_engine ( )

Returns the document ready to submit to the search engine.

Exceptions
coding_exception
Return values
array

◆ export_for_template() [1/2]

core_search\document::export_for_template ( \renderer_base  $output)

Export the document data to be used as a template context.

Adding more info than the required one as people might be interested in extending the template.

Although content is a required field when setting up the document, it accepts '' (empty) values as they may be the result of striping out HTML.

SECURITY NOTE: It is the responsibility of the document to properly escape any text to be displayed. The renderer will output the content without any further cleaning.

Parameters
renderer_base$outputThe renderer.
Return values
array

◆ export_for_template() [2/2]

templatable::export_for_template ( renderer_base  $output)
inherited

Function to export the renderer data in a format that is suitable for a mustache template.

This means:

  1. No complex types - only stdClass, array, int, string, float, bool
  2. Any additional info that is required for the template is pre-calculated (e.g. capability checks).
Parameters
renderer_base$outputUsed to do a final render of any components that need to be rendered for export.
Return values
stdClass|array

◆ format_string_for_engine()

static core_search\document::format_string_for_engine (   $string)
static

Formats a string value for the search engine.

Search engines may overwrite this method to apply restrictions, like limiting the size. The default behaviour is just returning the string.

Parameters
string$string
Return values
string

Reimplemented in search_solr\document.

◆ format_text()

core_search\document::format_text (   $text)
protected

Formats a text string coming from the search engine.

By default just return the text as it is:

  • Search areas are responsible of sending just plain data, the search engine may append HTML or markdown to it (highlighing for example).
  • The view is responsible of shortening the text if it is too big
Parameters
string$textText to format
Return values
stringHTML text to be renderer

Reimplemented in search_solr\document.

◆ format_text_for_engine()

static core_search\document::format_text_for_engine (   $text)
static

Formats a text value for the search engine.

Search engines may overwrite this method to apply restrictions, like limiting the size. The default behaviour is just returning the string.

Parameters
string$text
Return values
string

◆ format_time_for_engine()

static core_search\document::format_time_for_engine (   $timestamp)
static

Formats the timestamp preparing the time fields to be inserted into the search engine.

By default it just returns a timestamp so any search engine could just store integers and use integers comparison to get documents between x and y timestamps, but search engines might be interested in using their own field formats. They can do it extending this class in search_xxx::document.

Parameters
int$timestamp
Return values
string

Reimplemented in search_solr\document.

◆ get()

core_search\document::get (   $field)

◆ import_time_from_engine()

static core_search\document::import_time_from_engine (   $time)
static

Returns a timestamp from the value stored in the search engine.

By default it just returns a timestamp so any search engine could just store integers and use integers comparison to get documents between x and y timestamps, but search engines might be interested in using their own field formats. They should do it extending this class in search_xxx::document.

Parameters
string$time
Return values
int

Reimplemented in search_solr\document.

◆ is_set()

core_search\document::is_set (   $field)

Checks if a field is set.

Member Data Documentation

◆ $enginefields

array core_search\document::$enginefields = array()
staticprotected

Any fields that are engine specifc.

These are fields that are solely used by a search engine plugin for internal purposes.

Field names should be prefixed with engine name to avoid potential conflict with core fields.

Uses same format as fields above.

◆ $isnew

bool core_search\document::$isnew = false
protected

Should be set to true if document hasn't been indexed before.

False if unknown.

◆ $optionalfields

array core_search\document::$optionalfields
staticprotected
Initial value:
= array(
'userid' => array(
'type' => 'int',
'stored' => true,
'indexed' => true
),
'groupid' => array(
'type' => 'int',
'stored' => true,
'indexed' => true
),
'description1' => array(
'type' => 'text',
'stored' => true,
'indexed' => true,
'mainquery' => true
),
'description2' => array(
'type' => 'text',
'stored' => true,
'indexed' => true,
'mainquery' => true
)
)

All optional fields docs can contain.

Although it matches solr fields format, this is just to define the field types. Search engine plugins are responsible of setting their appropriate field types and map these naming to whatever format they need.

◆ $requiredfields

array core_search\document::$requiredfields
staticprotected

All required fields any doc should contain.

We have to choose a format to specify field types, using solr format as we have to choose one and solr is the default search engine.

Search engine plugins are responsible of setting their appropriate field types and map these naming to whatever format they need.

◆ SCHEMA_VERSION

int const core_search\document::SCHEMA_VERSION = 2017091700

Change list (for engine implementers): 2017091700 - add optional field groupid.

Schema version number (update if any change)
