Complex query

How is it possible with wwwgetz (SRS 4 or SRS 5) and the Query Form 
to have answer to the following (not very complex) query ?

Description    : topoisomerase
Organism       : homo sapiens
Keyword        : ! EST

with ! EST  => error
with * ! EST    very long query and timeout.

Message :
While trying to retrieve the URL: http://www.infobiogen.fr/srs5/cgi-bin/wgetz The following error was encountered: 
       No Object Data 
This means that: The remote server closed the connection before 
sending any data.

With 2 queries and combining them (in the Query Manager)  no problem, 
but this is not optimized !

[libs={embl emblnew}-Description: topoisomerase*] & [libs-Organism: homo sapiens*] 
[libs={embl emblnew}-Keywords: EST*] 

Query "Q1 ! Q2" found 43 entries 


Elsewhere with ACNUC  query is relatively quick  :

$ acnuc -b genbank
             ****     ACNUC Data Base Content      ****
         GenBank Rel. 103 (15 Octoger 1997) Last Updated: Nov  4, 1997
1,200,675,858 bases; 1,828,859 sequences; 229,363 subseqs; 142,660 references.
Command? (H for command list)
select
k=@topoisomerase at II@  et sp=homo sapiens et no k=EST

Sequence list named LIST1      contains     15 seqs (among which      6 subseqs)
