Terminal triple CC bond searches

[zarn...@gmail.com]

Dear Support, 

I have found an issue with Bingo substructure searches and terminal triple bonds.

If I search for CC#C I only find the structures with internal triple bonds, where as CC#C[H] finds all the terminal triple bonds.

This doesn't happen with CC=C searches because this finds internal and terminal double bonds. 

Hope that makes sense. 

Regards, Karl

I have similar issues with N#C searches

N#C finds for example

N#Cc1nc(C)ccc1F 

O=Cc1cc(c([nH]1)C)C#N

Cc1c(cc[nH]1)C#N

N#Cc1c(C)c[nH]c1C

N#Cc1ccc([nH]1)C(=O)C

N#CCCNc1ccccc1Cl

N#CC(=C1OCCO1)C#N

N#CC(C(c1c(C)cc(cc1C)C)C/C(=N/NC(=O)N)/c1cccs1)

where as N#CC doesn't find any of these.

Thanks, Karl

Another example of the N#C search issue is 

This sub search CCN1CCCCCCC1  or CN1CCCCCCC1 or N1CCCCCCC1

finds N#CCN1CCCCCCC1

where as N#CC doesn't 

but N#C does.
