multiple indexing example

[kostasgalexiou]

Hi,

I want to index a vcf file based on fields "#CHROM" and "POS", representing column1 and column2 in the file, respectively. How can I modify the json file so that I can provide the name of the field instead of its number? And secondly, how do I perform a zq query based on the multiple index?

Thanks
Kostas
