pilog question about combined indexes

[C K Kashyap]

Hi,
I tried the following

: (? (select (@Tel) ( (mob +CuSu "37 176 86303")  ) ))


 @Tel={C1}

-> NIL

: (? (select (@Tel) ( (mob +CuSu "37 176 86303" tel +CuSu "37 176 86303")  )
))

-> NIL


The first query returned as expected. The second one I believe means - look
for "37 176 86303" either in tel or in mob. I expected the second query to
return the same result as the first query - If I read the "Combined Indexes
section of https://software-lab.de/doc/select.html correctly that is :)



What am I missing?

Kashyap
