Airgentic Help
Filters are controls visitors use to narrow search results.
Examples include:
Filters depend on indexed Search Fields. Before a field can be used as a filter, it must exist in the search index and be enabled as a search filter.
Open Search Configuration > Fields to configure Search Fields. For a typical filter, enable Show this field as a search filter, then use Search Configuration > Filters to review and tune filter-specific settings.
Some advanced filter options may initially be visible only to Airgentic support or superusers.
| Filter type | Example |
|---|---|
| Simple list | Format: Online, In person, Blended |
| Hierarchy | Subject: Engineering > Civil |
| Range or date | Date: Past month, Past year |
| Toggle | Show only available courses |
Not every service needs every filter type.
Most website filters use List of checkboxes/buttons with Match any selected value.
The field editor shows an example beside the selected Filter style so you can see the kind of control visitors will get.
The Sort by dropdown in Advanced settings controls the order of values inside a filter.
Common choices:
Most filters should use Match any selected value. If a visitor selects Online and Evening, results can match either value.
Use Must match all selected values only for multi-valued fields where the same page can contain several values and the visitor expects every selected value to be present. For example, a course tagged with both Online and Evening would match when both are selected.
Enable Multi-valued when a single page or document can have more than one value for the field. If the website stores those values in one metadata string, set Split multi-value field on to the separator used by the website, such as a comma.
Use Hierarchy / drill-down path as the field type when the value has levels. The hierarchy delimiter and maximum depth are shown in Advanced settings only for hierarchy fields.
Examples:
| Requirement | Recommended setup |
|---|---|
| Delivery filter with values such as Online and In person | Keyword field, list filter. |
| A page with multiple delivery values in one metadata field | Enable Multi-valued and set the split separator. |
| Subject area drill-down such as Engineering > Civil | Hierarchy field, hierarchical filter. |
Different search scopes may show different filters.
For example:
This helps keep the search interface relevant for each type of result.
For example, the Programs scope can show Delivery, Sector, and Credential, while the News scope can show different filters.
Configure scope-specific filter visibility on Search Configuration > Scopes. Category mappings are managed separately on the Categories tab.
See Configuring Search Scopes.
Filter values should be clean and consistent.
For example, these should usually become one value:
onlineOnlineOnline Learningweb-basedAirgentic can normalise values using canonical labels, synonyms, casing rules, and allowed-value lists.
Changing how a filter is displayed may not require reprocessing. Changing the field used by a filter usually does.
Typical examples:
| Change | Typical impact |
|---|---|
| Rename filter label | No reprocess. |
| Change filter visibility | No reprocess. |
| Add filter from existing indexed field | No reprocess. |
| Add new extracted field for filter | Re-extract or reindex. |
| Change value normalisation | Re-extract or reindex. |
Some advanced filter options, such as value normalisation and scope-specific visibility, may initially be managed by Airgentic support or superusers.
