Advanced Query Help
New retrieval criteria
Advanced query works exactly the same way as standard query. The main and only
difference resides in the presentation of the retrieval query form. The
advanced one presents more selection criteria and then is more condensed as
the standard ones. New criteria are the following :
We will try also through this help to explain some details on the database
data structure to give you the opportunity to make more accurate searches.
- 3 new criteria to specify a reactant
- possibility to select several processes
- bibliographic criteria
In previous versions (earlier than 3.1) when specifying a reactant,
one was obliged to give a formula. This restriction
is now obsolete and search can be done only specifying a ionization state as
giving 35+ for example. Nevertheless, if more than 100 reactants satisfy your request, the program will stop, asking you to restrict your query. This of
course now also apply to standard query.
Note : when specifying a reactant, don't forget that by default, the system
search molecules in ground state : no ionization
and no "strong" excitation.
Reactants : for reactants 3 new fields are available :
- Chemical elements : just specify from 1 to 3 reactants
that you would
like in the molecule. Don't misunderstand, elements here apply only to the
reactant and not to the process. If every elements in a reactant is in the
process, not every element of the process will
be in the molecule.
- Chemical families : just as above, but for chemical
- Number of elements : number of chemical elements inside
the molecule. For
example HNO3 as 3 elements. Here again don't misunderstand with the
number of element of the process
One can specify here one to three physical processes or properties.
- Year : one can give a specific year or a bound of years. Year can
be written on 2 or 4 digits (1995 is same as 95).
- Author : Search can be done on authors' name. Name must be written fisrt name first, then initials. Names in GAPHYOR are truncated to 15 characters and type is non sensitive.
For the search one can also use the truncation character "*". It can be useful if you don't know the exact initials of the name. Truncation character can only be used at the end of the name. Then a search on "magne*" will give differents
papers with one author named "Magne L" or "Magnenat T" or "Magnera N".
Search on authors works the same way as a search on reactants. On the first pass a list of the bibliographic references which
match the request is proposed. One can select one of these references or every
- JournalOne must entered (non sensitive case) the GAPHYOR code of
the journal he is looking for.
