Exclude Replaced or Discontinued UIDs from an reutils.esearch operation

Question

[Ram]

Hi,

I'm using reutils to programmatically query NCBI's Gene database. Sometimes, I get multiple matches for a search (duh) and this list of results includes entries that have been discontinued or replaced (as shown in the Status filter on the Web UI below)

My question is:

How can I add a filter to my esearch call (or to the search term), so the search is restricted to only live/Current items? I can filter once I get the results when I make an esummary call, but can I do it at the esearch level?

My query term is UNQ6494[Gene Name] AND Homo sapiens[ORGN], and the r command is esearch(term="UNQ6494[Gene Name] AND Homo sapiens[ORGN]", db="gene")

Thank you!

Wonderful! I was trying live[Status] but alive[Prop] it was! Thank you!
