Re: [Exist-open] ft:query facets and options

[Boris L. <bo...@da...>]

     Hello Gus,

     take a look at 
https://github.com/eeditiones/tei-publisher-app/blob/master/modules/query.xql, 
TEI Publushers uses json format for options, as you can see here

     declare variable $query:QUERY_OPTIONS := map {
     "leading-wildcard": "yes",
     "filter-rewrite": "yes"
     };

     and here:

     declare function query:options($sortBy as xs:string*) {
     map:merge((
         $query:QUERY_OPTIONS,
         map {
             "facets":
                 map:merge((
                     for $param in 
request:get-parameter-names()[starts-with(., 'facet-')]
                     let $dimension := substring-after($param, 'facet-')
                     return
                         map {
                             $dimension: request:get-parameter($param, ())
                         }
                 ))
         },
         if ($sortBy) then
             map { "fields": ($sortBy, $config:default-fields) }
         else
             map { "fields": $config:default-fields }
         ))
     };

    I would also prefer the <option> in XML, maybe someone else can help.

     Boris
