Search endpoint misses `Filters` and `Parents properties`

[joepio]

• See endpoint
• No Filters and Search params

pub struct SearchQuery {
    /// The text search query entered by the user in the search box
    pub q: Option<String>,
    /// Maximum amount of results
    pub limit: Option<usize>,
    /// Only include resources that have one of these resources as its ancestor
    #[serde_as(as = "Option<StringWithSeparator::<CommaSeparator, String>>")]
    pub parents: Option<Vec<String>>,
    /// Filter based on props, using tantivy QueryParser syntax.
    /// e.g. `prop:val` or `prop:val~1` or `prop:val~1 AND prop2:val2`
    /// See https://docs.rs/tantivy/latest/tantivy/query/struct.QueryParser.html
    pub filters: Option<String>,
    pub include: Option<bool>,
}

TODO

• Create properties (in the server ontology)
• Add them to urls.rs
• Add them to the search Endpoint definition
