Query using Like "*" with null field

[PATRICK]

Im trying to set up this query where has client name, project name. for client name field always will have information but for project name only some has, other register a empty, so on my query I say : like"*" & [txtclient]... so all appear, but if I move to second field and put this syntax like"*" & [txtprojectname] then only register with information on the field is showing up, but I want them all even if even if doesn't have information.

Need to create a field in query with expression that handles the Null then apply the LIKE criteria to that constructed field.

ProjNameAdj: Nz([txtprojname],"")
