Please see the below examples:

# Approach 1
Query
|> where([...], cond_a and cond_b)
|> or_where([...], cond_a and cond_c)
|> or_where([...], cond_a and cond_d)
|> or_where([...], cond_a and cond_e)

# Approach 2
Query
|> where([...], cond_a)
|> where([...], cond_b or cond_c or cond_d or cond_e)

Isn’t there another way to write this query without repeating cond_a apart from the approach2?

Something like:

Query
|> where_always([..], cond_a)
|> or_where([...], cond_b)
|> or_where([...], cond_c)
|> or_where([...], cond_d)
|> or_where([...], cond_e)

Edit: where_always of course is purely imaginary and means the condition should be met first and always then we can consider the or_where conditions.
