Multiple search fields per table for the search endpoint

[MattiasSp]

When defining a search model for the search endpoint, the current searchField parameter can only handle one field per table definition, like in this example from the docs:

{
    table: 'Adresser',
    searchField: 'NAMN',
    schema: 'public',
    geometryName: 'geom',
    gid: 'OBJECTID'
}

To search more than one field in the same table, the definition has to be repeated, and worse the query will be run once for each definition:

{
    table: 'Adresser',
    searchField: 'NAMN',
    schema: 'public',
    geometryName: 'geom',
    gid: 'OBJECTID'
},
{
    table: 'Adresser',
    searchField: 'POPNAMN',
    schema: 'public',
    geometryName: 'geom',
    gid: 'OBJECTID'
}

It would be great if each table only had to be defined and queried once, using a searchFields array:

{
    table: 'Adresser',
    searchFields: ['NAMN', 'POPNAMN'],
    schema: 'public',
    geometryName: 'geom',
    gid: 'OBJECTID'
}
