Search resources

Filter

The Filter Resource is a json object that contains the information related to a filter. It is very similar to the facet value resource, with some adjustments, as follows:

Name	Type	Description
properties	Object	A dictionary object containing the properties and values.
remove	Search Link	A hyperlink to the resource that represents the search with this filter removed. Note: if there are other filters depending on the respective filter, these will also be removed by clicking this link.
Entity	Link	A hyperlink to the resource that represents the entity behind this filter value (if any)

Example of a Non-Ranged Filter Resource

{
    "properties": {
        "title": "display text/value for the filter value",
        "matches": 96,
        "identifier": "filter value identifier - could be Redis entity id or Redis definition name or solr field name",
        "operator": "filter operator",
        "positive": true if the filter is positive, false if it's negative,
        "type": "type of the solr field on which this filter is applied",
        "ranged": false
    },
    "remove": {
        "query": "myQueryWithThisFilterAndAllTheDependentFiltersRemoved",
        "href": "http://<hostname>/api/search?q=myQueryWithThisFilterAndAllTheDependentFiltersRemoved&skip=10&take=10"
    },
    "Entity": {
        "href": "http://<hostname>/api/entities/entityId"
    }
}

Example of a Ranged Filter Resource

{
    "properties": {
        "title1": "display text/value for the lower filter value",
        "identifier1": "identifier for the lower filter value",
        "title2": "display text/value for the higher filter value",
        "identifier2": "identifier for the higher filter value",
        "operator": "Between",
        "positive": true if the filter is positive, false if it's negative,
        "type": "type of the solr field on which this filter is applied",
        "ranged": true
    },
    "remove": {
        "query": "myQueryWithThisFilterAndAllTheDependentFiltersRemoved",
        "href": "http://<hostname>/api/search?q=myQueryWithThisFilterAndAllTheDependentFiltersRemoved&skip=10&take=10"
    },
    "Entity": null
}

Filter Operators

The filter operators is a set of values used to identify the operation desired as follows:

Oprator	Description
Equals	when wanting perfect equality, unless the filter is a full-text filter, in which case use a "Contains" operator. This operator is used with non-ranged filters.
Contains	the filter value is contained by the field value. This is used for text filters, only with non-ranged filters.
StartWith	the field value starts with the filter value. This is used for text fields, only with non-ranged filters.
EndsWith	the field value ends with the filter value. This is used for text fields only with non-ranged filters.
LessThan	the filter value is smaller than the field value. This is used for date and number fields, only with non-ranged filters.
GreaterThan	the filter value is larger than the field value. This is used for date and number fields, only with non-ranged filters.
Between	the field value is between the 2 filter values. This is used for date and number fields, only with ranged filters.
