Information
about the search function
The search function
implemented in Zoographia Germaniae is a non-indexing search
script written in PHP that only searches HTML
documents of a given animal group. You can use the
search function to find documents that contain
names or other query words within a taxon. For
example, the query Drosophila entered on the
Drosophilidae main page will return all documents
assigned to this family that contain the word
Drosophila. However, the same input on e.g. the
Nymphalidae main page will not return results.
The search
script has certain general features and limits:
- The search script cannot
recognize or process special characters (e.g. German umlauts ä, ö, ü, or
the ligated sz, ß). If your query contains these characters, the search
script will not return results.
- All query
terms are linked by AND; thus the script will
only return HTML documents that contain all
query terms.
- The
maximum number of separate query terms is
limited to 3. All terms beyond this limit will
be ignored. The maximum length for the entire
query is 70 characters.
(Example: Entering Drosophila
melanogaster fasciata nigriventris will
generate the query Drosophila AND melanogaster
AND fasciata).
- The
minimal number of letters in a query or query
term is 2. Empty queries or queries containing
terms comprising only a single character will
not be processed.
- The search
script does not discriminate between upper and
lower case letters.
(Example: The query drosophila
will return documents that contain drosophila or
Drosophila).
- By
default, the search script performs wild-card
searches for all query terms.
(Example: The query Droso melano
will return documents that contain Drosophila
melanogaster,
but also documents that contain e.g. Drosophilidae
and melanotarsis,
or Pseudodrosophila and submelanoides.
- In certain
cases, wild-card searches may be too
unspecific and return too many documents. If
you wish to search for exact matches, please
type a single dot . before your query
(don´t type a blank between the dot and
your query). All query terms will then be used
for exact matching rather than wild-card
matching.
(Example: The query .Meigen Tipula
will only match documents that contain these two
words exactly, but not words like meigeni or
tipulaeformis).
- The search
results will be displayed on a new page, but a
link to the previous page is provided on the
results page.
- The
performance (=speed) of the search script
depends on the current processor load of the
server. Thus, the performance may vary
substantially, even for the same query depending on the time of day and server traffic. If you
experience long waiting times, please try
again a little later.
