How can I query the database?
There are three ways to search the database:
  • You can do a full-text search by entering search term(s) in the field below the main menu on the left.
  • You can do a quick search in the database section at the top of the page. This allows you to conduct a full-text search, optionally restricted to a specific technology field or a project type.
  • You can do an advanced search in the database's technologies section. The search field is located on the right-hand side of the page and allows you to combine a full-text search (of all texts in the database) and an indexed search.

Advanced Search
Advanced Search allows you to combine a full-text search (of all texts in the database) and an indexed search of the following:·
  • technology field
  • type of traction and/or transportation
  • evaluation criteria
  • technology data's creation or update date
You will notice that some search fields are preceded by a field containing the logical (or Boolean) operators, AND and OR. If you would like to use this function, please enable 'javascript' in your browser. Your browser should be IE 5.0 and higher or Netscape 6.2 and higher.
  • To conduct a full-text search, enter at least 3 letters of the word you are looking for.
  • To search within a specific technology field or for a specific saving strategy, select one of the items in the "technology field" drop down menu.
  • To look for a special type of traction and/or transportation, select one of the items in the corresponding drop down menu.
  • To include specific evaluation criteria in your search, please first select the criterion in the left-hand drop down menu. You will then find corresponding evaluation options in the drop down menu on the right-hand side.
  • To look for technologies with a specific creation or update date, please first choose one of the operators: >,<, between. Depending on the operator, you will have to enter one or two dates into the boxes on the right.
  • After pressing the button 'perform search', you will find a list of results at the end of the page.
  • You can reset your search options by pressing the button 'reset fields'.

How can I compare technologies?
You can compare technologies by performing a search with specific, user-defined search criteria. There are different ways to narrow your search results. The easiest way is to open the advanced search form (see above) and include specific criteria in your search. By clicking on a technology name in the result list which appears below the search mask, you can display the evaluation part of the technology. On the following page you can click on the plus icons to open a specific part of the information you are interested in. To display the same evaluation criteria for the other pre-selected technologies, you can use the navigation tool at the top of the page (previous / next technology).
