Indexing lookup table

*The lookup table name is "mimu_*town_*vt". I have already created a previous question name as "selected_*townships_*id". After selecting the previous question, I want to see the next question. I have already created a name as "selected_*town_*vt", by using the lookup table I mentioned before. Please provide a query for indexing the lookup table to see the "town_*vt" list in the "selected_*town_*vt" question. And also please instruct me where I must add the query in the question field. Thanks.

The lookup table I have shown you is a sample table. In my actual lookup table, there are over 10000 rows. So, please provide me a query for indexing so that my application not have slow issue.

Dear All, I am trying to create questions for my locations. I am stuck in the process when I use the lookup tables. Even just for one more week, I have tried. Why is Commcare more difficult than KoBo Collect when we filter the location for those questions? In KoBo Collect, it is very easy, just by uploading a CSV file to the media. If you have a comment, please let me know that. Thank you all.
