#Why are there some missing indexes? This happens when there are no items to add to the index. To create an index it is required to create an index schema. The schema is created dynamically based on the fields of the items that are going to be added to the index. As there are no items to add, the schema is not created as well as the index.

#Why there are queries to the index which does not exist? Different parts of Sitecore functionality may rely on the index in question. The index will be still queried every time to check if it is created and if there are any items in it.

#Can I manually create these empty indexes? Yes, however they will probably get deleted next time a rebuild is kicked off. Azure Search does not allow to modify the schema of the existing fields but only allows to add new fields to the schema. However, the schema is strictly limited to 1000 fields only. So the indexer will first delete the index and then try to recreate it if it can find any fields on the index.

#Can I add dummy items for it to create the indexes?

Yes!

sitecore-marketing-asset-index

1. Create a media item or just use the default /sitecore/media library/Default-Website/sc-logo item
2. Create an asset under /sitecore/system/Marketing Control Panel/Taxonomies/Asset if you don't have any already
3. Set an asset in the Marketing asset field of the media item.
4. Assign the Download event to this media item: Content Editor -> Media item -> Analyze tab -> Attributes -> Events -> Download
5. The "Deploy" tab of the media item should now show, you can then click it to deploy the marketing asset (which in turn will index the new item).

###sitecore-fxm-index

1. Create a dummy domain matcher item under /sitecore/system/Marketing Control Panel/FXM
2. Set the domain to a dummy value http://dummy

sitecore-marketing-asset-index

On Azure Search, the sitecore_marketing_asset_index_web and sitecore_marketing_asset_index_master do not get created. Instead the indexed data gets combined with and stored on the sitecore_marketingdefinitions_web and sitecore_marketingdefinitions_master indexes.

sitecore-testing-index

Similar to the above, the data is combined and stored with the sitecore-suggested-test-index

sitecore-fxm-index

By default there are no items under /sitecore/system/Marketing Control Panel/FXM and therefore I assume the index doesn't get created as there are no items.

In general if you are having trouble with these indexes, the first step is to make sure marketing definitions have deployed succesfully via the Control Panel. In my experience this will sort out 99% of issues related to this. If this doesn't solve the issue then you will need to post a new question with the error message(s) from the logs during indexing.
