List Collections from JSON endpoint

[paul.mcguinness]

Hi,

Is there a way I can get a list of available web collections from a JSON endpoint. This is to allow the user to specify which collection they wish to search against.

Thanks, Paul.

Hi Paul,

You can customise the display of the default collection template to do this (as long as you don't need a JSON mime type sent).

Note: you can only have a single template to display the no collection listing, so if you change this to return JSON you'll lose the HTML list that's returned by default.

You will also need back end access to your Funnelback server.

To return a JSON list of collections do the following:

1. Log in to your Funnelback server and change to the $SEARCH_HOME/web/templates/modernui folder.

2. Create a file called no-collection.ftl containing the following code:

   <#escape x as x?json_string>
   <#compress>
   {
   "collections": [
   <#list AllCollections as oneCollection>
   {
   "name": "${oneCollection.configuration.value("service_name")}",
   "id": "${oneCollection.id}",
   "link": "?collection=${oneCollection.id}"
   }<#if oneCollection?has_next>,
   
   ]
   }
   
   

3. Access the following URL: http://YOURFBSERVER/s/search.html (or https://YOURFBSERVER/s/search.html)

Hi @paul.mcguinness -

Pre-query, the raw JSON output will expose all component collections available within a given meta collection, which could get you a little closer:

"question": {
    "query": null,
    "originalQuery": null,
    "collection": {
        "id": "example-meta",
        "profiles": {
            "_default": {
                "id": "_default",
                "facetedNavConfConfig": null,
                "padreOpts": null
            }
        },
        "facetedNavigationConfConfig": null,
        "facetedNavigationLiveConfig": null,
        "textMinerBlacklist": [ ],
        "metaComponents": [
            "example-web",
            "example-youtube"
        ],
        "type": "meta"
    },

Note the question.collection.metaComponents output there.
