Hints how to handle problems arising from the WWW interface
ATTENTION! Extensive query results (which are e.g. obtained
after not having supplied any, or merely insufficient, search criteria)
can cause the WWW browser to run into memory problems. These problems
have been observed especially on local PC platforms, PCs under NICE and Macintoshes.
YOU SHOULD THEN RESTRICT YOUR QUERY BY MEANS OF APPROPRIATE SEARCH PATTERNS !!
THEREFORE:
- Avoid the exclusive specification of wildcard "*"
- Avoid to start the query when not having supplied any search criteria,
as long as the standard option
('search criteria automatically enclosed in wildcard "*"')
is checked.
- Avoid the exclusive specification of single characters
as long as the standard option
('search criteria automatically enclosed in wildcard "*"')
is checked.
- Generally avoid queries where a large number
of query results could be expected,
as e.g. in "*ger?t*", "gerät"
(...gerät...) (the german word for "equipment"); "meß"; etc.
- If you would like to get some better survey
over existing keys, please do not start
the query without having specified any
search criteria; rather use a display
of consecutive DFG keys (which could be
obtained e.g. with an entry like "11*") and sort
by DFG key (in order to get e.g. 110,
111, 112, ..., 119, as well as upper group "11-"). Or use the display of
alphabetically consecutive key texts
(which could be obtained e.g. with an entry like
"a*") and sort by key text.
(In each case choose option
'Search criteria as pre-assigned'.)
- A good method is to get some better survey over existing keys by
means of upper groups (e.g. "11-")
and main groups (e.g. "1--"),
and thereafter to examine single upper groups through
display of corresponding equipment groups,
i.e. by pre-assignment of a DFG key analogous to "11*".
In case it should not be possible to avoid a
query with extensive query results,
please use the WWW interface by means of the
WWW browsers netscape& and mosaic&
on a central UNIX machine (e.g. x4u2),
where no problems have been observed so far!
