If you're willing to put in a little time and effort, it's possible you don't need the indexes.
You linked to the Hungary Civil Registration collection here:
That page contains a very long list of document collections, organized by town or location of origin. As Budapest is large relative to the other towns and cities, its records are spread across multiple collections, one for each district, of which there appear to be at least 25.
Each collection contains multiple rolls, for births (Születtek), marriages (Házasultak), and deaths (Halottak), with each roll covering one or more years. I examined a few of the Budapest rolls, and while they do not contain any index pages at the beginning of the roll, they do appear to be in chronological order.
My suggestion for a plan of attack is to locate all of the Budapest collections that cover the time period in question, and then with each, do this:
- Find the Házasultak roll that covers 1911.
- Jump or scroll to 24 February 1911.
- Search several pages before and after for your people.
- If not found, move to the next Budapest collection.
Of course, if you know which district of Budapest they were married in, it will be much easier.
Using that technique, you can find the marriage of Taussig, Német Károly, to Kafka-Samfai, Mária Emma (elvált = divorced) in the 6th district of Budapest on image 742 of Film #004430102 at https://www.familysearch.org/ark:/61903/3:1:S3HY-DRN9-46B?i=741&cc=1452460&cat=826283

The rest of the 6th district records are here: https://www.familysearch.org/search/catalog/826283 If the family stayed in this location and had children, there may be more records to find.
I don't speak or read Hungarian, but for simple things like phrases on vital records documents, Google Translate isn't too bad. I noticed that the death certificate contains the word "elvált," which means "divorced," so it appears that your Dr. Taussig was divorced before he died.
@JPmiaou, a native Hungarian speaker, offers the following translated transcription:
