The search function in the online database

You can search in the databases using two methods:
  • Search via the database registers
  • Search using logical combinations
  •  

    Search using logical combinations

    The database has up to nine registers in which the data sets are indexed on the basis of content factors and ordered alphabetically.

    Selecting a register

    As a result, you will receive an extract from the selected register, which will also inform you how many data sets there are to each keyword in the register.


    Spelling of register entries


    References to other entries

    Some entries provide references to other entries. These can be recognised by the reference arrow "->". If you click on the left part of the entry, you will receive the data set from which the entry has been generated.

    If you click on the right-hand part, i.e. the reference, you will trigger a further register production; in other words, you will receive, as the first entry, another register extract with the keyword referred to. To go to the relevant title sets, it is necessary in the case of person and organisation names to go one step higher in the register (because the entry only leads to the person or organisation entry). This can be done by entering the name in the search field and selecting a new item in the register.
     
     

    Meaning of the special symbol "*" behind the entries

    Some entries in the registers are marked with the indicator "*". These are entries on person or organisations in which the given form (e.g. Verein Deutscher Ingenieure) and the relevant references (e.g. VDI) are contained.


    What else is it possible to do?

    Command field [Change to]
    Before the register extract, there are links to the other registers of the database. If you activate one of them, you will be able to see that register. The alphabetical starting point is the same as for the original register, as is also the number of lines displayed.
     
    Command field [Next page]
    With this command, you can go to the next page in the register. The next lines of the register are generated. ('n' stands for the number of lines originally entered in the search mask.)
     
    Command field [Show abbreviated entries]
    If you click on this command, you will be shown the same extract from the register, but in the form of an abbreviated title. The abbreviated title display shows one line per register entry with the following information:
     

    Search using logical combinations

    Some register keywords of a general nature can often lead to a large number of data sets. To restrict the search in such cases, you can search the database by entering several search words which are linked together. The result is displayed in the form of an abbreviated title list or, where there is only one match, with the full title.

    Entering search words

    With the four entry fields for "Search word", you can search for person names, title keywords, signatures and book titles .

     

    Logical links using and or or

    Search is carried out using the link word and . In terms of the number of matches, this means that all the search words given must occur in the title set. By selecting or, the search request is broadened: at least one of the search words must occur in the title set.
     

    The search mode truncated or exact

    The search mode using logical links is pre-set to truncated . All entries are displayed which match the search word or are longer than the search word.
    If only those entries are wanted which correspond exactly to the search word, it is necessary to change the search mode to exact .
