[MINITOC]

#### Why does asset _x_ not show up?
* In CELUM, try logging in as the backend user - if you can't see it there, it's a permission issue.
* If it's not that, 9 times out of 10 it's the cache. Clear the cache under Administration > System Tasks > Anura > Flush all caches. Don't forget about your browser's cache as well!
* When it's still not showing up, it may be hidden through a globalFilter, customSearchProvider or a custom search term in the front-end.

#### My facet count does not reflect the actual number of assets that were found?
* The facet index is probably out of sync - there's a few events that we don't get told about (such as changed permissions). Use Administration > System Tasks > Anura > Recreate facet search index (and clear the cache ^^)
* Further common troubleshooting steps can be found in the [troubleshooting section](/anura/backend/faceted-search#troubleshooting).

#### I needed to do a special integration, so I changed something in jquery.anura.xyz.js file xD
* **DON'T**! You won't be able to update to the next release without porting your stuff → ask us to add an **event** or a **callback** or a **setting**, we're more than happy to help.
* If you want to go deeper, we're also happy to provide you with access to our git repo to create a merge request.

#### Do I need a separate webserver to run a standalone portal?
* No. All the front-end does is serve a bit of HTML and some JS-Files - you can put it on anything you got that serves http-requests. Everything else happens on the CELUM server and in the browser. [Here's a diagram](/anura/frontend#who-does-the-work).

#### Wow, that's a lot! Where do I even get started? (or: I ain't got time for all that!)
* [We've got you covered, here's a complete layout to start with](/anura/frontend#complete-layout) - tweak some IDs and colors and you're good to go!

#### But I'm using _$frameworkDuJour_, I can't (or don't want to) load these components. What now?
* You can build your own components and can still use and benefit from the stability, cacheability and all of the features of our API - here's an [example](https://www.hansgrohe-group.com/de/pressrelease).

#### Can I use this to stream videos?
* Yes, depending on how much traffic you expect. By default, CELUM's video player is used, but this only scales to a limited extent. When you do a lot with videos, we recommend that you use some sort of [videoPlayerProvider](/anura/backend#anura-1-video-player-provider). Out of the box we support YouTube, Vimeo and MovingImage through their respective backstage packages.

#### Wait, so everyone can access the content made available through the endpoints?
* Yes, this was designed as a public image gallery to put on your website.  You can however add authentication through a [tokenVerifier](/anura/backend#anura-1-token-verifier), which requires an access token to be sent with every API request. Out of the box we support static tokens (like CORA uses), a status code callback and login through the CELUM login screen (thereby implicitly also LDAP ans SAML). Authenticating a user against a session they might have in your CMS requires a bit of engineering on both ends.
* **But I want to know who downloaded my assets‽**
  * **low** hurdles: Require their e-mail address when downloading through [downloadHandler=anuraMailInputDownloader](/anura/backend#anura-1-download-handler)
  * **medium** hurdles: Require them to place an order for the assets through [downloadHandler=anuraAssetOrderDownloader](/anura/backend#anura-1-download-handler) (you can also make them fill out more fields, e.g. usage. Order can either be released automatically or reviewed by one or more humans)
  * **hight** hurdles: Require them to login to CELUM through [downloadHandler=anuraLoginFilterDownloader](/anura/backend#anura-1-download-handler), which requires an account (which in turn requires them to register first). You can also only require a login for certain formats (e.g. high-res needs login, low-res is available to everyone)
  * **custom** hurdles: Use a combination of [tokenVerifier](/anura/backend#anura-1-token-verifier) and the events that the front-end generates to set up custom tracking.

#### Where do you get all the labels from?
* We get them from CELUM (here's a [list](/anura/frontend/misc#translations)), so you can override any label you don't like in the `customMessages_xy.properties` as usual. If you only want to override it for anura but not in CELUM, prefix the key with `anura.`, e.g. `anura.paging.page=P.` leaves the CELUM UIs `paging.page=Page` untouched.

#### "since" is newer than the latest version I can find

* This indicates that this feature has not officially been released yet. So when it says "since 2.9" it might already be available in some very recent dot-release of 2.8, which may additionally depend on which branch as well. When in doubt, ask us.

#### Can I run multiple instances of the same plugin on one page?

Yes you can, as long as you keep an eye on the following:
* The containers you load the plugins into should have a unique ID, e.g. `<div id="table1">` and `<div id="table2">`
* When using deep-links, each "group" must have a unique `state` setting (preferably something short, e.g. `t1` and `t2`)
* To connect a navigation component to a main view, overwrite `callback` in order to talk to the "correct" instance
  ```js
  var table1 = $('#table1').anuraTable({/*...*/, state: 't1'});
  var search1 = $('#search1').anuraSearch({
      /*...*/,
      state: 't1',
      callback: function (server, search_query) {
          table1.anuraTable({search: {custom: search_query}, locale: lang});
      }
  });
  
  var table2 = $('#table2').anuraTable({/*...*/, state: 't2'});
  var search2 = $('#search2').anuraSearch({
      /*...*/,
      state: 't2',
      callback: function (server, search_query) {
          table2.anuraTable({search: {custom: search_query}, locale: lang});
      }
  });
  ```
