OR logical operator is not symmetric in keyword based search in SCREENER: is this a bug?

in Eikon Data APIs

Let us say I want to find all private companies that either contain the keyword "well being" or "well-being" in the Business Description. The way to do this using the Eikon API is the following:


syntax = "SCREEN(U(IN(Private(OrgType(COM, UNK, MKP)))),"\
           "Contains(TR.BusinessSummary,'well-being') OR Contains(TR.BusinessSummary,'well being'),"\
           "CURN=USD, TR.OrganizationStatusCode=Act)"
fields = ["TR.CommonName", "TR.BusinessSummary"]
df, e = ek.get_data(syntax, fields)

Now, ['well-being' OR 'well being'] and ['well being' OR 'well-being'] should give the exact same result. But it does not. The following code shows the issue:

syntax_1 = "SCREEN(U(IN(Private(OrgType(COM, UNK, MKP)))),"\
           "Contains(TR.BusinessSummary,'well-being') OR Contains(TR.BusinessSummary,'well being'),"\
           "CURN=USD, TR.OrganizationStatusCode=Act)"

syntax_2 = "SCREEN(U(IN(Private(OrgType(COM, UNK, MKP)))),"\
           "Contains(TR.BusinessSummary,'well being') OR Contains(TR.BusinessSummary,'well-being'),"\
           "CURN=USD, TR.OrganizationStatusCode=Act)"

fields = ["TR.CommonName", "TR.BusinessSummary"]

df_1, e = ek.get_data(syntax_1, fields)
df_2, e = ek.get_data(syntax_2, fields)
print(len(df_1))
print(len(df_2))

len(df_1) is 62 and len(df_2) is 349.

Seems like this is a bug? Or am I doing something wrong?

@zoya faberov I think you might know this. Thank you.
