Pivot Templates

Search uses database indices on special pivot columns and full text fields.

These columns and text fields are extracted in a process called pivoting. This is done a short period after a resource has been updated.

The content of the pivot columns is determined by a template. This template is called pivot/pivot.tpl (in mod_base) and is rendered using a catinclude. This makes it possible to have your own unique indexing per category.

The pivot/pivot.tpl template consists of multiple blocks. Each block corresponds to a pivot column. The block is rendered for determining the pivot’s content.

The following blocks are defined:

a, b, c and d

These blocks are used for the full text index. Block a contains more important texts than block b, c or d. Per default the title and other essential texts are shown in block a, and block d is used for related texts (think titles of connected resources). The default pivot template uses the following catincluded templates for the different blocks:

• pivot/_title_text.tpl for block a
• pivot/_main_text.tpl for block b
• pivot/_block_text.tpl for block c
• pivot/_related_text.tpl for block d

title

The title used for database sorting etc. Per default the lowercased title in the selected pivot language or the default site language.

related_ids

The ids of all related resources and categories. This is a full text index used for finding resources that are similar to some other resource. All matching resource ids should be prefixed with zpo and category ids with zpc (for example zpo1234). The catincluded template pivot/_related_ids.tpl is used for extracting these ids. This template also adds the id of the content group as a related resource.

address_street, address_city, address_postcode, address_state, address_country

The address to be used for searches. Defaults to the related address_… properties with a fallback to the mail_address_… properties. The country should be the two letter ISO code, not the country’s descriptive text.

name_first, name_surname

If the resource is a person then this should contain the first name and surname.

gender

The gender of the person, currently a single letter. For example: f, m or ?.

date_start, date_end

The start or end date associated with the resource. This should be in a parseable format, which will be done automatically when echoing a date directly. Make sure UTC is used as the timezone (note that the timezone will be set to UTC when pivoting).

date_start_month_day, date_end_month_day

A four digit number representing the month and day for the date start and date end. Think of an index for birthdays, without exposing the birth year. Defaults to {{ id.date_start|date:"md" }} and {{ id.date_end|date:"md" }}.

location_lat, location_lng

The latitude and longitude of the resource location. This should be empty or a floating point number. Defaults to {{ id.computed_location_lat|default:id.location_lat }} and {{ id.computed_location_lng|default:id.location_lng }}

date_repivot

The date and time this resource should be repivoted. This is useful if some resources (like events) should be indexed with lower priorities after a certain date. A pivot task will be scheduled at the specified date. Per default no repivot will be scheduled.
